Thelia authentication bypass vulnerability

GHSA-g8pg-33v4-9r96

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (thelia/thelia 2.1.3), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: GHSA-g8pg-33v4-9r96

Advisory: Thelia authentication bypass vulnerability
IDs: GHSA-g8pg-33v4-9r96
Record: https://patchnext.com/advisories/ghsa-g8pg-33v4-9r96 (revision 1, source checked 26 Oct 2026, 14:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: thelia/thelia 2.1.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist thelia/thelia: affected >= 2.0.0-beta1, < 2.1.3; fixed in 2.1.3

## Suggested inspection (read-only)
- Packagist thelia/thelia: check the installed version with your package manager.

## 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 thelia/thelia.
- 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
