{"cve":"CVE-2026-52796","nvd":{"published":"2026-06-24T21:16:55.270","modified":"2026-06-25T21:16:27.133","status":"Deferred","description":"Gogs is an open source self-hosted Git service. Prior to 0.14.3, specially crafted issue index pattern can cause a panic when rendering, resulting in denial of service. In internal/markup/markup.go, RenderIssueIndexPattern renders the issue index pattern to a link using com.Expand, which is not safe: when the configured pattern contains an opening brace { but no closing brace }, strings.Index(template, \"}\") returns -1 and the subsequent slice template[:-1] triggers a panic. Once such a pattern is set, any page in the affected repository that contains an issue index reference such as #1 becomes unavailable. This vulnerability is fixed in 0.14.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","score":3.5},"cwes":["CWE-1336"],"references":["https://github.com/gogs/gogs/security/advisories/GHSA-4j89-2c4f-44c6","https://github.com/gogs/gogs/security/advisories/GHSA-4j89-2c4f-44c6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-52796","score":0.00284,"percentile":0.21001,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4j89-2c4f-44c6","url":"https://osv.dev/vulnerability/GHSA-4j89-2c4f-44c6","summary":"Gogs has DoS in rendering issue index pattern","modified":"2026-07-21T13:30:31.792639325Z","packages":[{"ecosystem":"Go","name":"gogs.io/gogs","purl":"pkg:golang/gogs.io/gogs","ranges":["<0.14.3"],"fixed":["0.14.3"]}]},{"id":"GO-2026-5124","url":"https://osv.dev/vulnerability/GO-2026-5124","summary":"Gogs has DoS in rendering issue index pattern in gogs.io/gogs","modified":"2026-06-25T18:45:23.711845921Z","packages":[{"ecosystem":"Go","name":"gogs.io/gogs","purl":"pkg:golang/gogs.io/gogs","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).
