{"cve":"CVE-2026-43983","nvd":{"published":"2026-05-12T15:16:15.797","modified":"2026-06-17T10:50:09.680","status":"Analyzed","description":"Pocket ID is an OIDC provider that allows users to authenticate with their passkeys to your services. Prior to 2.6.0, The createTokenFromRefreshToken function (oidc_service.go) validates the refresh token's cryptographic integrity but does not re-validate the user's current authorization state before issuing new tokens. This allows (1) the client to refresh the token indefinitely after authorization revocation, (2) the refresh token to continue to work after the account is disabled, and (3) the token to work after the client is removed from the group. This vulnerability is fixed in 2.6.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-285","CWE-613"],"references":["https://github.com/pocket-id/pocket-id/security/advisories/GHSA-w6p7-2fxx-4f44","https://github.com/pocket-id/pocket-id/security/advisories/GHSA-w6p7-2fxx-4f44"],"products":["pocket-id:pocket_id"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43983","score":0.00247,"percentile":0.16108,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w6p7-2fxx-4f44","url":"https://osv.dev/vulnerability/GHSA-w6p7-2fxx-4f44","summary":"Pocket ID: OIDC refresh token flow bypasses authorization revocation, account disabling, and group restrictions","modified":"2026-08-18T15:10:43.198975218Z","packages":[{"ecosystem":"Go","name":"github.com/pocket-id/pocket-id/backend","purl":"pkg:golang/github.com/pocket-id/pocket-id/backend","ranges":["<0.0.0-20260419162744-978ac87deffe"],"fixed":["0.0.0-20260419162744-978ac87deffe"]}]},{"id":"GO-2026-6119","url":"https://osv.dev/vulnerability/GO-2026-6119","summary":"Pocket ID: OIDC refresh token flow bypasses authorization revocation, account disabling, and group restrictions in github.com/pocket-id/pocket-id/backend","modified":"2026-08-18T15:00:16.079935360Z","packages":[{"ecosystem":"Go","name":"github.com/pocket-id/pocket-id/backend","purl":"pkg:golang/github.com/pocket-id/pocket-id/backend","ranges":["<0.0.0-20260419162744-978ac87deffe"],"fixed":["0.0.0-20260419162744-978ac87deffe"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
