Denial of Service in apostrophe
What to do
Vendor fix available. Upgrade each affected package to the fixed version on its release line (apostrophe 2.97.1), 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.

Source description
As published by the source; long descriptions are shortened.
Versions of apostrophe prior to 2.97.1 are vulnerable to Denial of Service. The apostrophe-jobs module sets a callback for incoming jobs and doesn't clear it regardless of its status. This causes the server to accumulate callbacks, allowing an attacker to start a large number of jobs and exhaust system memory. Recommendation Upgrade to version 2.97.1 or later.

# Patch Next advisory brief: GHSA-pv6r-vchh-cxg9 Advisory: Denial of Service in apostrophe IDs: GHSA-pv6r-vchh-cxg9 Record: https://patchnext.com/advisories/ghsa-pv6r-vchh-cxg9 (revision 2, source checked 26 Oct 2026, 12:08 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Unrated Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor fix available; fixed versions by package: apostrophe 2.97.1. A vendor fix does not mean a deployment is fixed. ## Affected components - npm apostrophe: affected < 2.97.1; fixed in 2.97.1 ## Suggested inspection (read-only) - `npm ls apostrophe --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`. ## 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 apostrophe. - 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 - Verified: https://osv.dev/vulnerability/GHSA-pv6r-vchh-cxg9 (OSV record GHSA-pv6r-vchh-cxg9 lists affected ranges: npm apostrophe >=0 <2.97.1 (fixed)) - Verified: https://github.com/advisories/GHSA-pv6r-vchh-cxg9 (GitHub-reviewed advisory GHSA-pv6r-vchh-cxg9 lists affected ranges: npm apostrophe >=0 <2.97.1) Commands are suggestions: review each one before running it.
