CVE-2026-27606 WRITEUP CRITICAL
Rollup <2.80.0/3.30.0/4.59.0 - Path Traversal
Rollup is a module bundler for JavaScript. Versions prior to 2.80.0, 3.30.0, and 4.59.0 of the Rollup module bundler (specifically v4.x and present in current source) is vulnerable to an Arbitrary File Write via Path Traversal. Insecure file name sanitization in the core engine allows an attacker to control output filenames (e.g., via CLI named inputs, manual chunk aliases, or malicious plugins) and use traversal sequences (`../`) to overwrite files anywhere on the host filesystem that the build process has permissions for. This can lead to persistent Remote Code Execution (RCE) by overwriting critical system or user configuration files. Versions 2.80.0, 3.30.0, and 4.59.0 contain a patch for the issue.

CVE-2026-27610 WRITEUP MEDIUM
Parse Dashboard 7.3.0-alpha.42-9.0.0-alpha.7 - Privilege Escalation
Parse Dashboard is a standalone dashboard for managing Parse Server apps. In versions 7.3.0-alpha.42 through 9.0.0-alpha.7, the `ConfigKeyCache` uses the same cache key for both master key and read-only master key when resolving function-typed keys. Under specific timing conditions, a read-only user can receive the cached full master key, or a regular user can receive the cached read-only master key. The fix in version 9.0.0-alpha.8 uses distinct cache keys for master key and read-only master key. As a workaround, avoid using function-typed master keys, or remove the `agent` configuration block from your dashboard configuration.
CVSS 5.3
CVE-2026-27611 WRITEUP MEDIUM
FileBrowser Quantum <1.1.3/1.2.6 - Auth Bypass
FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to versions 1.1.3-stable and 1.2.6-beta, when users share password-protected files, the recipient can completely bypass the password and still download the file. This happens because the API returns a direct download link in the details of the share, which is accessible to anyone with JUST THE SHARE LINK, even without the password. Versions 1.1.3-stable and 1.2.6-beta fix the issue.
CVSS 6.5
CVE-2026-27612 WRITEUP MEDIUM
repostat < 1.0.1 - Reflected Cross-Site Scripting via RepoCard Component
Repostat is a React component to fetch and display GitHub repository info. Prior to version 1.0.1, the `RepoCard` component is vulnerable to Reflected Cross-Site Scripting (XSS). The vulnerability occurs because the component uses React's `dangerouslySetInnerHTML` to render the repository name (`repo` prop) during the loading state without any sanitization. If a developer using this package passes unvalidated user input directly into the `repo` prop (for example, reading it from a URL query parameter), an attacker can execute arbitrary JavaScript in the context of the user's browser. In version 1.0.1, the use of dangerouslySetInnerHTML has been removed, and the repo prop is now safely rendered using standard React JSX data binding, which automatically escapes HTML entities.
CVSS 6.1
CVE-2026-27614 WRITEUP CRITICAL
Bugsink < 2.0.13 - Unauthenticated Stored Cross-Site Scripting via Pygments Line Handling
Bugsink is a self-hosted error tracking tool. In versions prior to 2.0.13, an unauthenticated attacker who can submit events to a Bugsink project can store arbitrary JavaScript in an event. The payload executes only if a user explicitly views the affected Stacktrace in the web UI. When Pygments returns more lines than it was given (a known upstream quirk that triggers with Ruby heredoc-style input), `_pygmentize_lines()` in `theme/templatetags/issues.py:75-77` falls back to returning the raw input lines. `mark_safe()` at line 111-113 is then applied unconditionally - including to those unsanitized raw lines. Since DSN endpoints are public by Sentry protocol, no account is needed to inject. The payload sits in the database until an admin looks at the event. Successful exploitation requires that the attacker to be able to submit events to the project (i.e. knows the DSN or can access a client that uses it), the Bugsink ingest endpoint is reachable to the attacker, and an administrator explicitly views the crafted event in the UI. Under those conditions, the attacker can execute JavaScript in the administrator’s browser and act with that user’s privileges within Bugsink. Version 2.0.13 fixes the vulnerability.
CVSS 9.3
CVE-2026-27621 WRITEUP MEDIUM
TypiCMS < 16.1.7 - Stored Cross-Site Scripting via SVG File Upload
TypiCMS is a multilingual content management system based on the Laravel framework. A Stored Cross-Site Scripting (XSS) vulnerability exists in the file upload module of TypiCMS prior to version 16.1.7. The application allows users with file upload permissions to upload SVG files. While there is a MIME type validation, the content of the SVG file is not sanitized. An attacker can upload a specially crafted SVG file containing malicious JavaScript code. When another user (such as an administrator) views or accesses this file through the application, the script executes in their browser, leading to a compromise of that user's session. The issue is exacerbated by a bug in the SVG parsing logic, which can cause a 500 error if the uploaded SVG does not contain a `viewBox` attribute. However, this does not mitigate the XSS vulnerability, as an attacker can easily include a valid `viewBox` attribute in their malicious payload. Version 16.1.7 of TypiCMS Core fixes the issue.
CVSS 5.4
CVE-2026-27627 WRITEUP HIGH
Karakeep 0.30.0 - Stored Cross-Site Scripting via Reddit Metascraper Plugin
Karakeep is a elf-hostable bookmark-everything app. In version 0.30.0, when the Reddit metascraper plugin returns `readableContentHtml`, the HTML parsing subprocess uses it directly without running it through DOMPurify. Every other content source in the crawler goes through Readability + DOMPurify, but the Reddit path skips both. Since this content ends up in `dangerouslySetInnerHTML` in the reader view, any malicious HTML in the Reddit response gets executed in the user's browser. Version 0.31.0 contains a patch for this issue.
CVSS 8.2
CVE-2026-27628 WRITEUP HIGH
pypdf < 6.7.2 - Denial of Service via Infinite Loop
pypdf is a free and open-source pure-python PDF library. Prior to 6.7.2, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires reading the file. This has been fixed in pypdf 6.7.2. As a workaround, one may apply the patch manually.
CVSS 7.5
CVE-2026-27636 WRITEUP HIGH
FreeScout < 1.8.206 - Authenticated Remote Code Execution via .htaccess Upload
FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.206, FreeScout's file upload restriction list in `app/Misc/Helper.php` does not include `.htaccess` or `.user.ini` files. On Apache servers with `AllowOverride All` (a common configuration), an authenticated user can upload a `.htaccess` file to redefine how files are processed, enabling Remote Code Execution. This vulnerability can be exploited on its own or in combination with CVE-2026-27637. Version 1.8.206 fixes both vulnerabilities.
CVSS 8.8
CVE-2026-27637 WRITEUP CRITICAL
FreeScout < 1.8.206 - Predictable Token Authentication Bypass via MD5 Token
FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.206, FreeScout's `TokenAuth` middleware uses a predictable authentication token computed as `MD5(user_id + created_at + APP_KEY)`. This token is static (never expires/rotates), and if an attacker obtains the `APP_KEY` — a well-documented and common exposure vector in Laravel applications — they can compute a valid token for any user, including the administrator, achieving full account takeover without any password. This vulnerability can be exploited on its own or in combination with CVE-2026-27636. Version 1.8.206 fixes both vulnerabilities.
CVSS 9.8
CVE-2026-27639 WRITEUP MEDIUM
Mercator < 2026.02.22 - Authenticated Stored Cross-Site Scripting via Unescaped Blade Directives
Mercator is an open source web application designed to enable mapping of information systems. A stored Cross-Site Scripting (XSS) vulnerability exists in Mercator prior to version 2026.02.22 due to the use of unescaped Blade directives (`{!! !!}`) in display templates. An authenticated user with the User role can inject arbitrary JavaScript payloads into fields such as "contact point" when creating or editing entities. The payload is then executed in the browser of any user who views the affected page, including administrators. Version 2026.02.22 fixes the vulnerability.
CVSS 5.4
CVE-2026-27641 WRITEUP CRITICAL
Flask-Reuploaded <1.5.0 - Path Traversal
Flask-Reuploaded provides file uploads for Flask. A critical path traversal and extension bypass vulnerability in versions prior to 1.5.0 allows remote attackers to achieve arbitrary file write and remote code execution through Server-Side Template Injection (SSTI). Flask-Reuploaded has been patched in version 1.5.0. Some workarounds are available. Do not pass user input to the `name` parameter, use auto-generated filenames only, and implement strict input validation if `name` must be used.
