Title
filebrowser through 2.63.23 Stale Share Link via File Rename
Summary
filebrowser through 2.63.23 does not remove share records when a shared file is renamed (only deletion triggers share cleanup). The share record is keyed by path, so it survives the rename and remains dormant (returning 404 while the path is empty). When any new, unrelated file later appears at the original shared path — via re-upload, another user with create permission, or a hook — the stale public share link serves that new file under the original link's password and expiry settings, unexpectedly exposing it.

Summary
File Browser versions from 2.63.6 through 2.63.23 fail to clean up public share links when a privileged user deletes another user's shared file. Attackers can access the surviving share link to retrieve new unrelated content uploaded to the same path without authentication.

Title
Cross-Document Parser State Contamination in misp-stix
Summary
A parser state isolation vulnerability in misp-stix could cause data from a previously processed STIX document to be retained and incorporated into the MISP event generated from a subsequent document when the same parser instance is reused.
Several STIX 1 and STIX 2 parser components maintained per-document state that was not completely cleared between conversions. In the STIX 2 parser, galaxy and galaxy-cluster information, including custom galaxy clusters, could survive a parser reset and subsequently be associated with objects from another bundle.
The STIX 1 parsers were affected by the same underlying state-management issue. Depending on the parser type, retained information could include galaxies, references, passive DNS bookkeeping, package titles, dates, and timestamps. As a result, parsing a second STIX package with an already-used parser could produce a MISP event containing information that was present only in the previously processed package. For example, a generated event could inherit passive DNS records from an earlier document, reference unrelated galaxy information, combine titles from different packages, or use timestamps originating from another conversion.
The issue primarily affects applications using the misp-stix API directly and reusing parser instances across independent STIX documents. Normal conversion entry points that instantiate a new parser for each file are not affected by this particular reuse scenario.
An attacker able to influence documents processed by such a long-lived parser could potentially cause information from one conversion to contaminate a subsequent MISP event. This can affect the integrity of generated threat intelligence, resulting in incorrect associations, misleading contextual information, or unrelated indicators being attributed to an event. In environments where consecutive documents have different access controls or distribution scopes, the retained state could additionally result in limited disclosure of information from a previously processed document.
Successful exploitation depends on the consuming application reusing the same parser instance and on the ordering of processed documents, which increases attack complexity. No direct availability impact or code execution is involved.

Title
multer vulnerable to Denial of Service via file descriptor leak on aborted uploads
Summary
multer is a middleware for handling multipart/form-data in Node.js. In version 2.2.0, when a disk-backed upload is aborted or truncated before the write stream finishes, multer's disk storage engine removes the visible file but does not close the underlying write file descriptor, leaving a deleted but still open descriptor. A remote attacker able to reach an upload route using the built-in disk storage can send repeated aborted or malformed multipart uploads, each one leaking a file descriptor and retaining disk blocks until the process exits, which can exhaust resources and cause a denial of service. The issue is fixed in multer 2.3.0, which closes the destination write stream on abnormal source termination and defers cleanup until the stream has closed. Upgrade to multer 2.3.0 to remediate.

Title
Rocq Prover through 9.2.0 Universe Checking State Desynchronised After Module Close
Summary
Rocq Prover does not restore the universe graph's copy of the universe checking flag when a module that locally disabled the check is closed. Local Unset Universe Checking inside a module is expected to last only until the module ends, and the global flag is restored, but the universe graph keeps its own copy which is left disabled. The two views then disagree: Test Universe Checking reports the check as enabled while the kernel continues to accept universe-inconsistent terms. With the constraint between two universes no longer enforced, Hurkens' paradox applies and yields a proof of False, from which any proposition follows. The proof uses no axioms, plugins or unsafe features once the module has closed, and Print Assumptions reports it as closed under the global context, so neither the assumption audit nor the flag query reflects the actual kernel state. No fix is available.

Title
FUXA Business Logic Flaw: Role Deletion Without User Assignment Cleanup
Summary
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.3, DELETE /api/roles removes role definitions through server/runtime/users/usrstorage.js but does not remove the deleted role identifier from each user's info.roles array or the runtime usersMap cache. If a permission configuration still references that identifier, an affected user can retain authorization rights that an administrator intended to revoke, causing residual privilege, inconsistent access-control state, and misleading audit results. This issue is fixed in version 1.3.3.
