CVE-2026-59227 WRITEUP MEDIUM WRITEUP
Open WebUI: POST /api/v1/images/edit bypasses the global image-edit switch and the per-user image-generation permission
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.11 before 0.10.0, POST /api/v1/images/edit required only a verified account and did not enforce the global image-edit switch or the per-user image-generation permission, allowing a non-admin user to invoke server-side image editing with administrator-configured provider credentials. This issue is fixed in version 0.10.0.
CVSS 4.3
CVE-2026-59880 WRITEUP HIGH WRITEUP
Immutable.js: Hash-collision algorithmic complexity denial of service in Immutable.Map/Set
Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, Immutable.Map and Immutable.Set keep keys that share the same 32-bit hash in a HashCollisionNode collision bucket that is scanned linearly, allowing an attacker who controls keys inserted into a Map, such as through Immutable.Map(obj), Immutable.fromJS(obj), state.merge(userObject), or mergeDeep, to craft many colliding keys and degrade insertion and lookup to consume disproportionate CPU. This issue is fixed in versions 4.3.9 and 5.1.8.

CVE-2026-59702 WRITEUP CRITICAL WRITEUP
repomix - Server-Side Request Forgery via Unvalidated Repository URLs in POST /api/pack
repomix contains a server-side request forgery vulnerability in the POST /api/pack endpoint that allows unauthenticated attackers to make arbitrary outbound requests. The endpoint fails to properly validate http://, https://, and file:// URLs before passing them to git clone, enabling attackers to access private network addresses, GCP metadata services, or local filesystem paths.
CVSS 9.3
CVE-2026-59703 WRITEUP HIGH WRITEUP
repomix - Local File Inclusion via file:// URL Scheme in Git Clone Endpoint
repomix contains a local file inclusion vulnerability in the git clone endpoint that allows unauthenticated attackers to read arbitrary local git repositories. The isValidRemoteValue function in src/core/git/gitRemoteParse.ts fails to block file:// URLs, permitting attackers to supply file:// scheme URLs that bypass validation and are passed directly to git clone, enabling unauthorized access to all tracked file contents on the server filesystem.
CVSS 7.5
CVE-2026-60124 WRITEUP MEDIUM WRITEUP
MISP importModule missing authorization allows read-only users to modify events via misp_standard imports
An authorization bypass in MISP’s EventsController::importModule() allowed authenticated users or read-only API keys with event view access to persist data to events they were not allowed to modify. When an import module returned results in the misp_standard format, the write path did not verify event modification rights before saving the module output. This could allow a view-only user to inject or alter event data, impacting the integrity of MISP event content. The issue was fixed by enforcing the same modification-rights check used by related module result handling paths before processing misp_standard imports.
CVE-2026-60125 WRITEUP MEDIUM WRITEUP
importModule function in MISP ignores per-organisation import module restrictions
MISP’s importModule() path used getEnabledModule() to resolve a single import module by name, but this lookup did not enforce the per-organisation module restriction checked by getEnabledModules(). As a result, an authenticated user from an organisation that was not allowed to use a module restricted via Plugin.Import_<module>_restrict could still invoke that import module directly if they knew its name. This could allow unauthorised access to restricted import-module functionality and, depending on the module and the user’s event permissions, may allow unauthorised import or modification of event data through a module that should have been unavailable to the user’s organisation.
CVE-2026-58404 WRITEUP MEDIUM WRITEUP
Hugo security.http.urls deny rules bypassed by alternate IPv4 encodings
Hugo is a static site generator. From v0.162.0 through v0.163.0, the default security.http.urls policy denies requests to loopback, internal, and cloud-metadata IPv4 literals, but the deny rule only matched dotted-decimal notation, so alternate IPv4 encodings of the same addresses, including integer, hex, or octal, passed the policy. When a template passes an untrusted or data-derived URL to resources.GetRemote and the host platform uses the cgo system resolver, these encodings resolve to the blocked address, allowing build-time server-side requests to loopback and internal services, including the cloud-metadata endpoint in hosted or CI builds; the same check is reused on redirects, so the gap also applies to each redirect hop. This issue is fixed in v0.163.1.

CVE-2026-59712 WRITEUP HIGH WRITEUP
Leantime - Credential Disclosure via Unauthenticated JSON-RPC users.getUser Method
Leantime's Users::getUser method in the JSON-RPC API lacks proper authorization checks, allowing authenticated users to retrieve full user credential rows including password hashes, TOTP secrets, and session tokens. Attackers can exploit this by calling users.getUser with arbitrary user IDs to enumerate all accounts and obtain credentials for offline password cracking, 2FA bypass, and session hijacking.

CVE-2026-58578 WRITEUP MEDIUM WRITEUP
LobeChat < 2.2.10-canary.15 - Regular Expression Denial of Service in GitHub Skill Import
LobeChat before version 2.2.10-canary.15 contains a regular expression denial of service (ReDoS) vulnerability that allows authenticated attackers to block the Node.js event loop by supplying a catastrophic-backtracking pattern in a GitHub repository URL path during skill import. Attackers can craft a malicious basePath value containing unescaped regex metacharacters such as catastrophic-backtracking patterns, which are injected into a dynamically constructed regular expression in the findSkillMd function and executed synchronously against archive entries, denying service to all concurrent users for tens of seconds per request.
CVSS 6.5
CVE-2026-59098 WRITEUP MEDIUM WRITEUP
LobeChat 2.2.9 - Cross-User Document Disclosure via Unscoped RAG Semantic Search
LobeChat through 2.2.9 contains a broken access control vulnerability in the retrieval-augmented-generation semantic search functionality that allows authenticated attackers to access other users' data by exploiting missing user-identifier predicates in the chunk model semanticSearch method. Attackers can supply arbitrary victim file or knowledge-base identifiers through the chunk retrieval and chat knowledge-base paths to retrieve text content, file names, and metadata belonging to other users.
CVSS 6.5
CVE-2026-59100 WRITEUP MEDIUM WRITEUP
LobeChat 2.2.9 - Broken Object Level Authorization via Chat-Group Agent Operations
LobeChat through 2.2.9 contains a broken object level authorization vulnerability that allows authenticated attackers to access and modify other users' chat-group agent data by supplying arbitrary group identifiers. Attackers can invoke the getGroupAgents, updateAgentInGroup, and removeAgentsFromGroup operations without user-scoped predicates to read agent listings, modify agent roles and ordering, and remove agents from chat groups belonging to other users.
CVSS 5.0
CVE-2026-49119 WRITEUP HIGH WRITEUP
Gradio < 6.16.0 Path Traversal via FileExplorer.preprocess()
Gradio before 6.16.0 contain a path traversal vulnerability in the FileExplorer component's preprocess() method that allows unauthenticated attackers to escape the configured root directory by supplying path segments containing directory traversal sequences or absolute paths. Attackers can provide crafted path segments that cause os.path.join to discard the root_dir prefix entirely, resulting in arbitrary file read or exposure of sensitive files outside the intended directory.

CVE-2026-56422 WRITEUP CRITICAL WRITEUP
MISP Core: Mass Assignment and Object Re-ownership via Unvalidated Request Fields
Multiple MISP core controllers and model capture paths accepted client-controlled request fields such as primary keys (id) and ownership/scope foreign keys (event_id, org_id, user_id, sharing_group_id, galaxy_cluster_uuid, organisation_uuid, and related nested object identifiers) without consistently stripping, pinning, or revalidating them against the server-authorized object. In affected paths, an authenticated user with access to one authorized object could submit crafted REST or form payloads that caused MISP to save data against a different object than the one checked by the authorization logic. Depending on the endpoint, this could allow object overwrite, object re-parenting, ownership transfer, unauthorized sharing-group scoping, event/object injection, proposal retargeting, or stored attacker-controlled content appearing in another user’s context. The fixes harden affected create/edit/import flows by stripping client-supplied primary keys on create-only saves, re-pinning route- or database-authorized identifiers before save operations, validating effective sharing-group scope, and adding field whitelists where ownership fields must never be editable. The initial broad fix also added a central CRUDComponent::edit() primary-key re-pin so payload-supplied IDs cannot redirect saves away from the already-authorized row. GitHub’s patch for 7acf8220c describes this central issue as CRUDComponent::edit() copying supplied fields, including a payload primary key, onto the loaded record, allowing CakePHP save() to update an arbitrary row unless the loaded ID is re-pinned.

CVE-2026-57454 WRITEUP MEDIUM WRITEUP
Vim: Out-of-bounds Read with Text Properties
Vim is an open source, command line text editor. From 9.2.0320 until 9.2.0679, a crafted undo or swap file can store a virtual-text property whose offset and length point outside the line's property data. When Vim restores or displays such a line it converts the offset into a pointer and reads the virtual text without bounds checking, causing an out-of-bounds read that can crash Vim or disclose adjacent heap memory. This vulnerability is fixed in 9.2.0679.
