Prior to version 3000.10.3, an unauthenticated denial-of-service vulnerability exists in OliveTin’s OAuth2 login flow. Concurrent requests to /oauth/login can trigger unsynchronized access to a shared registeredStates map, causing a Go runtime panic (fatal error: concurrent map writes) and process termination. This allows remote attackers to crash the service when OAuth2 is enabled. This issue has been patched in version 3000.10.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-362","CWE-400","CWE-662"],"references":["https://github.com/OliveTin/OliveTin/commit/f044d90d5525c4c8e3f421b32ed7eff771c22d36","https://github.com/OliveTin/OliveTin/security/advisories/GHSA-45m3-398w-m2m9","https://github.com/OliveTin/OliveTin/security/advisories/GHSA-45m3-398w-m2m9"],"products":["olivetin:olivetin"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-28789","score":0.00453,"percentile":0.39351,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-45m3-398w-m2m9","url":"https://osv.dev/vulnerability/GHSA-45m3-398w-m2m9","summary":"OliveTin has unauthenticated DoS via concurrent map writes in OAuth2 state handling","modified":"2026-03-23T04:56:02.918420742Z","packages":[{"ecosystem":"Go","name":"github.com/OliveTin/OliveTin","purl":"pkg:golang/github.com/OliveTin/OliveTin","ranges":["<0.0.0-20260301235225-f044d90d5525c"],"fixed":["0.0.0-20260301235225-f044d90d5525c"]}]},{"id":"GO-2026-4586","url":"https://osv.dev/vulnerability/GO-2026-4586","summary":"OliveTin has unauthenticated DoS via concurrent map writes in OAuth2 state handling in github.com/OliveTin/OliveTin","modified":"2026-03-23T04:53:11.965649Z","packages":[{"ecosystem":"Go","name":"github.com/OliveTin/OliveTin","purl":"pkg:golang/github.com/OliveTin/OliveTin","ranges":["all versions"],"fixed":[]}]}],"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).
