LOWFides Webserver Vulnerable to SVG Bomb File Uploads
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Impact
The Fides webserver is vulnerable to a type of Denial of Service (DoS) attack. Attackers can exploit this vulnerability to upload zip files containing malicious SVG bombs (similar to a billion laughs attack), causing resource exhaustion in Admin UI browser tabs and creating a persistent denial of service of the 'new connector' page (datastore-connection/new).
This vulnerability affects Fides versions 2.11.0 through 2.15.1. Exploitation is limited to users with elevated privileges with the CONNECTOR_TEMPLATE_REGISTER scope, which includes root users and users with the owner role.
Patches
The vulnerability has been patched in Fides version 2.16.0. Users are advised to upgrade to this version or later to secure their systems against this threat.
Workarounds
There is no known workaround to remediate this vulnerability without upgrading.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ethyca-fides. 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.
Fix
Update ethyca-fides to 2.16.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3rw2-wfc8-wmj5 is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-3rw2-wfc8-wmj5 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-3rw2-wfc8-wmj5. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-3rw2-wfc8-wmj5 in your dependencies?
O3 detects GHSA-3rw2-wfc8-wmj5 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
