GHSA-f3rf-v9qm-9c89 affects the following packages: in2code/femanager (Packagist), in2code/femanager (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-f3rf-v9qm-9c89?

Update in2code/femanager to 5.5.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f3rf-v9qm-9c89 is resolved across your whole dependency graph.

How do I detect GHSA-f3rf-v9qm-9c89 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for in2code/femanager. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-f3rf-v9qm-9c89 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-f3rf-v9qm-9c89?

O3 pinpoints whether GHSA-f3rf-v9qm-9c89 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-f3rf-v9qm-9c89 actively exploited in the wild?

Yes. There are 2 known exploit references for GHSA-f3rf-v9qm-9c89, including 2 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-f3rf-v9qm-9c89?

GHSA-f3rf-v9qm-9c89 has an EPSS (Exploit Prediction Scoring System) score of 1.3%, placing it in the 67th 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-f3rf-v9qm-9c89?

GHSA-f3rf-v9qm-9c89 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-f3rf-v9qm-9c89 published, and has it been updated?

GHSA-f3rf-v9qm-9c89 was published on September 1, 2021 and was last updated on December 2, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Note: If SVG uploads are required, it is recommended to use the TYPO3 extension svg_sanitizer (added to TYPO3 core since versions 9.5.28, 10.4.18 and 11.3.0) to prevent upload of malicious SVG files or to set up a strict Content Security Policy for the destination folder of uploaded images.

Frequently Asked Questions

The extension allows by default to upload SVG files when a logged in frontend user uploads a new profile image. This may lead to Cross-Site Scripting, when the uploaded SVG image is used as is on the website. Note: If SVG uploads are required, it is recommended to use the TYPO3 extension svg_sanitizer (added to TYPO3 core since versions 9.5.28, 10.4.18 and 11.3.0) to prevent upload of malicious SVG files or to set up a strict Content Security Policy for the destination folder of uploaded images.
