Prior to 2.5.4, LinkRepository::update and CheckLinksCommand::checkLink do not check for private IPs. An authenticated user can read responses from internal services (AWS IMDSv1, cloud metadata, internal APIs) by creating a link with a public URL and then updating it to a private IP. The links:check cron job makes the request server-side without IP filtering. This can expose cloud credentials, internal service data, and network topology. This vulnerability is fixed in 2.5.4."}], "lastModified": "2026-04-14T20:27:53.187", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:linkace:linkace:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "1B6A4089-79B4-45A5-AF07-95336D858B6E", "versionEndExcluding": "2.5.4"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
