Which packages are affected by GHSA-gx46-mfgj-vm86?

Affected package information for GHSA-gx46-mfgj-vm86 is not yet fully mapped. Check the official advisory links for details.

How do I fix GHSA-gx46-mfgj-vm86?

Upgrade the affected component to the fixed release for GHSA-gx46-mfgj-vm86, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.

How do I detect GHSA-gx46-mfgj-vm86 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate GHSA-gx46-mfgj-vm86 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is GHSA-gx46-mfgj-vm86 actively exploited in the wild?

No public exploit code has been indexed for GHSA-gx46-mfgj-vm86 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-gx46-mfgj-vm86?

GHSA-gx46-mfgj-vm86 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 41th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-gx46-mfgj-vm86?

GHSA-gx46-mfgj-vm86 is classified as CWE-862 (CWE-862). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-gx46-mfgj-vm86 published, and has it been updated?

GHSA-gx46-mfgj-vm86 was published on September 22, 2026 and was last updated on October 21, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Kaneo versions 2.3.12 before 2.12.2 contain a missing authorization vulnerability that allows authenticated workspace members with viewer or member roles to delete and modify tasks beyond their assigned permissions by exploiting the bulk task endpoint that omits workspace permission checks. Attackers can send requests to the PATCH /api/task/bulk endpoint, which verifies only workspace membership without calling the role-based permission check enforced on all other task endpoints, to permanently delete all tasks or modify task status, priority, assignee, due date, and labels in a workspace.
