• CVE-2026-107394: 0.34% estimated exploitation activity in the next 30 days; percentile 27.42 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact Indico makes outgoing requests to user-provides URLs in various places. This is mostly intentional and part of Indico's functionality, but of course it is never intended to let you access "special" targets such as localhost or cloud metadata endpoints. The previous fix (CVE-2026-25738) did not cover an edge case so it was still possible to craft a URL that pointed to a local target but was accepted as valid by Indico. Patches You should to update to Indico 3.3.13 as soon as possible. See the docs for instructions on how to update. Workarounds If you do not have IPs that expose sensitive data without authentication (typically because you do not host Indico on AWS), this vulnerability doesn't impact you and you can ignore it (but please upgrade anyway). Also, only event organizers can access endpoints where SSRF could be used to actually see the data returned by such a request. So if you trust your event organizers, the risk is also very limited. For additional security, both…

# Patch Next advisory brief: CVE-2026-107394

Advisory: Indico: Incomplete Server-Side Request Forgery (SSRF) check
IDs: CVE-2026-107394, GHSA-2v95-h47v-g4x9
Record: https://patchnext.com/advisories/cve-2026-107394 (revision 3, source checked 26 Oct 2026, 13:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: indico 3.3.13. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI indico: affected < 3.3.13; fixed in 3.3.13

## Suggested inspection (read-only)
- `python -m pip show indico`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on indico.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
