CVE-2026-33025 WRITEUP HIGH
AVideo-Encoder is Vulnerable to Authenticated SQL Injection via ORDER BY Clause
AVideo is a video-sharing Platform. Versions prior to 8.0 contain a SQL Injection vulnerability in the getSqlFromPost() method of Object.php. The $_POST['sort'] array keys are used directly as SQL column identifiers inside an ORDER BY clause. Although real_escape_string() was applied, it only escapes string-context characters (quotes, null bytes) and provides no protection for SQL identifiers — making it entirely ineffective here. This issue has been fixed in version 8.0. To workaround this issue without upgrading, operators can apply a WAF rule to block POST requests where any sort[*] key contains characters outside [A-Za-z0-9_]. Alternatively, restrict access to the queue view (queue.json.php, index.php) to trusted IP ranges only.
CVSS 8.8
CVE-2026-33035 WRITEUP MEDIUM
Unauthenticated Reflected XSS via innerHTML in AVideo
WWBN AVideo is an open source video platform. In versions 25.0 and below, there is a reflected XSS vulnerability that allows unauthenticated attackers to execute arbitrary JavaScript in a victim's browser. User input from a URL parameter flows through PHP's json_encode() into a JavaScript function that renders it via innerHTML, bypassing encoding and achieving full script execution. The vulnerability is caused by two issues working together: unescaped user input passed to JavaScript (videoNotFound.php), and innerHTML rendering HTML tags as executable DOM (script.js). The attack can be escalated to steal session cookies, take over accounts, phish credentials via injected login forms, spread self-propagating payloads, and compromise admin accounts — all by exploiting the lack of proper input sanitization and cookie security (e.g., missing HttpOnly flag on PHPSESSID). The issue has been fixed in version 26.0.

CVE-2026-33036 WRITEUP HIGH
fast-xml-parser affected by numeric entity expansion bypassing all entity expansion limits (incomplete fix for CVE-2026-26278)
fast-xml-parser allows users to process XML from JS object without C/C++ based libraries or callbacks. Versions 4.0.0-beta.3 through 5.5.5 contain a bypass vulnerability where numeric character references (&#NNN;, &#xHH;) and standard XML entities completely evade the entity expansion limits (e.g., maxTotalExpansions, maxExpandedLength) added to fix CVE-2026-26278, enabling XML entity expansion Denial of Service. The root cause is that replaceEntitiesValue() in OrderedObjParser.js only enforces expansion counting on DOCTYPE-defined entities while the lastEntities loop handling numeric/standard entities performs no counting at all. An attacker supplying 1M numeric entity references like A can force ~147MB of memory allocation and heavy CPU usage, potentially crashing the process—even when developers have configured strict limits. This issue has been fixed in version 5.5.6.
CVSS 7.5
CVE-2026-33037 WRITEUP HIGH
WWBN AVideo has predictable default admin credentials in official Docker deployment path
WWBN AVideo is an open source video platform. In versions 25.0 and below, the official Docker deployment files (docker-compose.yml, env.example) ship with the admin password set to "password", which is automatically used to seed the admin account during installation, meaning any instance deployed without overriding SYSTEM_ADMIN_PASSWORD is immediately vulnerable to trivial administrative takeover. No compensating controls exist: there is no forced password change on first login, no complexity validation, no default-password detection, and the password is hashed with weak MD5. Full admin access enables user data exposure, content manipulation, and potential remote code execution via file uploads and plugin management. The same insecure-default pattern extends to database credentials (avideo/avideo), compounding the risk. Exploitation depends on operators failing to change the default, a condition likely met in quick-start, demo, and automated deployments. This issue has been fixed in version 26.0.
CVSS 8.1
CVE-2026-33038 WRITEUP HIGH
AVideo affected by unauthenticated application takeover via exposed web installer on uninitialized deployments
WWBN AVideo is an open source video platform. Versions 25.0 and below are vulnerable to unauthenticated application takeover through the install/checkConfiguration.php endpoint. install/checkConfiguration.php performs full application initialization: database setup, admin account creation, and configuration file write, all from an unauthenticated POST input. The only guard is checking whether videos/configuration.php already exists. On uninitialized deployments, any remote attacker can complete the installation with attacker-controlled credentials and an attacker-controlled database, gaining full administrative access. This issue has been fixed in version 26.0.
CVSS 8.1
CVE-2026-33039 WRITEUP HIGH
AVideo vulnerable to unauthenticated SSRF via HTTP redirect bypass in LiveLinks proxy
WWBN AVideo is an open source video platform. In versions 25.0 and below, the plugin/LiveLinks/proxy.php endpoint validates user-supplied URLs against internal/private networks using isSSRFSafeURL(), but only checks the initial URL. When the initial URL responds with an HTTP redirect (Location header), the redirect target is fetched via fakeBrowser() without re-validation, allowing an attacker to reach internal services (cloud metadata, RFC1918 addresses) through an attacker-controlled redirect. This issue is fixed in version 26.0.
CVSS 8.6
CVE-2026-33041 WRITEUP MEDIUM
AVideo has an Unauthenticated Password Hash Oracle via encryptPass.json.php
WWBN AVideo is an open source video platform. In versions 25.0 and below, /objects/encryptPass.json.php exposes the application's password hashing algorithm to any unauthenticated user. An attacker can submit arbitrary passwords and receive their hashed equivalents, enabling offline password cracking against leaked database hashes. If an attacker obtains password hashes from the database (via SQL injection, backup exposure, etc.), they can instantly crack them by comparing against pre-computed hashes from this endpoint. This endpoint eliminates the need for an attacker to reverse-engineer the hashing algorithm. Combined with the weak hash chain (md5+whirlpool+sha1, no salt by default), an attacker with access to database hashes can crack passwords extremely quickly. This issue was fixed in version 26.0.
CVSS 5.3
CVE-2026-33043 WRITEUP HIGH
AVideo affected by Session Hijacking via Unauthenticated Session ID Disclosure with Permissive CORS
WWBN AVideo is an open source video platform. In versions 25.0 and below, /objects/phpsessionid.json.php exposes the current PHP session ID to any unauthenticated request. The allowOrigin() function reflects any Origin header back in Access-Control-Allow-Origin with Access-Control-Allow-Credentials: true, enabling cross-origin session theft and full account takeover. This issue has been fixed in version 26.0.
CVSS 8.1
CVE-2026-33051 WRITEUP MEDIUM
Craft CMS Vulnerable to Stored XSS in Revision Context Menu
Craft CMS is a content management system (CMS). In versions 5.9.0-beta.1 through 5.9.10, the revision/draft context menu in the element editor renders the creator’s fullName as raw HTML due to the use of Template::raw() combined with Craft::t() string interpolation. A low-privileged control panel user (e.g., Author) can set their fullName to an XSS payload via the profile editor, then create an entry with two saves. If an administrator is logged in and executes a specifically crafted payload while an elevated session is active, the attacker’s account can be elevated to administrator. This issue has been fixed in version 5.9.11.
CVSS 5.4
CVE-2026-33062 WRITEUP HIGH
free5GC NRF Discovery EncodeGroupId Function Panics on Malformed group-id-list Parameter
free5GC is an open source 5G core network. free5GC NRF prior to version 1.4.2 has an Improper Input Validation vulnerability leading to Denial of Service. All deployments of free5GC using the NRF discovery service are affected. The `EncodeGroupId` function attempts to access array indices [0], [1], [2] without validating the length of the split data. When the parameter contains insufficient separator characters, the code panics with "index out of range". A remote attacker can cause the NRF service to panic and crash by sending a crafted HTTP GET request with a malformed `group-id-list` parameter. This results in complete denial of service for the NRF discovery service. free5GC NRF version 1.4.2 fixes the issue. There is no direct workaround at the application level. The recommendation is to apply the provided patch or restrict access to the NRF API to trusted sources only.
CVSS 7.5
CVE-2026-33063 WRITEUP HIGH
free5GC AUSF UE Authentication Panic on Nil SuciSupiMap Interface Conversion
free5GC is an open source 5G core network. free5GC AUSF prior to version 1.4.2 has is an Improper Null Check vulnerability leading to Denial of Service. All deployments of free5GC v4.0.1 using the AUSF UE authentication service (`/nausf-auth/v1/ue-authentications` endpoint) are affected. A remote attacker can cause the AUSF service to panic and crash by sending a crafted UE authentication request that triggers a nil interface conversion in the `GetSupiFromSuciSupiMap` function. This results in complete denial of service for the AUSF authentication service. The `GetSupiFromSuciSupiMap` function attempts to perform an interface conversion from `interface{}` to `*context.SuciSupiMap` without checking if the underlying value is nil. When `SuciSupiMap` is nil, the code panics with "interface conversion: interface {} is nil, not *context.SuciSupiMap". free5GC AUSF version 1.4.2 patches the issue. There is no direct workaround at the application level. The recommendation is to apply the provided patch or restrict access to the AUSF API to trusted sources only.

CVE-2026-25744 WRITEUP MEDIUM
OpenEMR: POST /api/.../vital Accepts Attacker-Supplied id and Overwrites Arbitrary Vitals
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, the encounter vitals API accepts an `id` in the request body and treats it as an UPDATE. There is no verification that the vital belongs to the current patient or encounter. An authenticated user with encounters/notes permission can overwrite any patient's vitals by supplying another patient's vital `id`, leading to medical record tampering. Version 8.0.0.2 fixes the issue.
CVSS 6.5
CVE-2026-25928 WRITEUP MEDIUM
OpenEMR Vulnerable to Path Traversal When Zipping DICOM Folders
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, the DICOM zip/export feature uses a user-supplied destination or path component when creating the zip file, without sanitizing path traversal sequences (e.g. `../`). An attacker with DICOM upload/export permission can write files outside the intended directory, potentially under the web root, leading to arbitrary file write and possibly remote code execution if PHP or other executable files can be written. Version 8.0.0.2 fixes the issue.
CVSS 6.5
CVE-2026-27166 WRITEUP MEDIUM
Discourse vulnerable to HTML injection via prohibited iframe URLs
Discourse is an open source discussion platform. Prior to versions 2026.3.0-latest.1, 2026.2.1 and 2026.1.2, insufficient cleanup in the default Codepen allowed iframes value allows an attacker to trick a user into changing the URL of the main page. This issue has been fixed in versions 2026.3.0-latest.1, 2026.2.1 and 2026.1.2. To workaround this issue, remove Codepen from the list of allowed iframes.
CVSS 4.1
CVE-2026-27454 WRITEUP MEDIUM
Discourse has check revision visibility on posts endpoint
Discourse is an open-source discussion platform. Prior to versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2, requesting /posts/:id.json?version=X bypassed authorization checks on post revisions. The display_post method called post.revert_to directly without verifying whether the revision was hidden or if the user had permission to view edit history. This meant hidden revisions (intentionally concealed by staff) could be read by any user by simply enumerating version numbers. Starting in versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2, Discourse looks up the PostRevision and call guardian.ensure_can_see! before reverting, consistent with how the /posts/:id/revisions/:revision endpoint already authorizes access. No known workarounds are available.
CVSS 5.3
CVE-2026-27491 WRITEUP MEDIUM
Discourse has a bypass of official warnings messages by non-staff users
Discourse is an open-source discussion platform. Prior to versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2, a type coercion issue in a post actions API endpoint allowed non-staff users to issue warnings to other users. Warnings are a staff-only moderation feature. The vulnerability required the attacker to be a logged-in user and to send a specifically crafted request. No data exposure or privilege escalation beyond the ability to create unauthorized user warnings was possible. Versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2 contain a patch. No known workarounds are available.
CVSS 4.3
CVE-2026-27570 WRITEUP MEDIUM
Discourse Vulnerable to Stored XSS via Shared AI Conversation Onebox
Discourse is an open-source discussion platform. Prior to versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2, the onebox method in the SharedAiConversation model renders the conversation title directly into HTML without proper sanitization. Versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2 contain a patch. As a workaround, tighten access by changing the `ai_bot_public_sharing_allowed_groups` site setting.
