Each worker process maintains its own\nin-memory session cache; logout only clears the cache of the single worker that handles the request (plus the shared database record). Other workers continue to honor the destroyed token\nfrom their stale in-memory copies until the session's lifetime expires. An attacker who has captured a valid token can therefore keep impersonating the user after the user has logged out.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5.3,"severity":"medium","source":"CNA: ERIC","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":5.3,"severity":"medium","source":"NVD: 85b1779b-6ecd-4f52-bcc5-73eac4659dcf","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"}],"modifiedAt":1793963837043,"publishedAt":1793960844656,"references":[{"source":"CNA: ERIC","tags":[],"url":"https://github.com/Ericsson/codechecker/security/advisories/GHSA-r42x-9wgw-cqc2"},{"source":"85b1779b-6ecd-4f52-bcc5-73eac4659dcf","tags":[],"url":"https://github.com/Ericsson/codechecker/security/advisories/GHSA-r42x-9wgw-cqc2"}],"remediation":[],"revision":"b5957f47e19cbc6920e54e1e94501bb57e7339eac21a7e13e174aff0b317350b","sources":[{"modifiedAt":1793960844656,"name":"CNA: ERIC","retrievedAt":1793963437115,"url":"https://www.cve.org/CVERecord?id=CVE-2026-84155"},{"modifiedAt":1793963837043,"name":"NVD","retrievedAt":1793967607972,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-84155"}],"ssvc":null,"status":"published","title":"Session Token Remains Valid After Logout in Multi-Worker Deployments","updatedAt":1793967607972}
