How do I fix GHSA-r99h-h44m-89m2?

Upgrade the affected component to the fixed release for GHSA-r99h-h44m-89m2, 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-r99h-h44m-89m2 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-r99h-h44m-89m2 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-r99h-h44m-89m2 actively exploited in the wild?

No public exploit code has been indexed for GHSA-r99h-h44m-89m2 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-r99h-h44m-89m2?

GHSA-r99h-h44m-89m2 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 11th 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-r99h-h44m-89m2?

GHSA-r99h-h44m-89m2 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-r99h-h44m-89m2 published, and has it been updated?

GHSA-r99h-h44m-89m2 was published on October 12, 2026 and was last updated on October 14, 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

Frappe ERPNext before 15.103.0 and 16.x before 16.12.0 contains a stored cross-site scripting vulnerability because the names of certain records are not properly neutralized when rendered on some dashboards, tools, and portals. Authenticated attackers can craft malicious record names that execute scripts in other users' browsers, enabling data access, modification, and token theft, especially against privileged users.
