A signed-in user who could read an issue could therefore add or remove reactions on a locked issue and its comments, bypassing the interaction restriction of the lock. Only reactions were affected; no content could be changed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":[],"references":["https://blog.gitea.com/release-of-28.2.0/","https://github.com/go-gitea/gitea/pull/39839","https://github.com/go-gitea/gitea/pull/39847","https://github.com/go-gitea/gitea/releases/tag/v28.2.0","https://github.com/go-gitea/gitea/security/advisories/GHSA-wx44-9m3m-rjqx"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-107686","score":0.00237,"percentile":0.14611,"date":"2026-10-25"},"kev":null,"osv":[],"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).
