This can lead to tokens remaining valid for longer than intended, increasing the window of opportunity for an attacker to use an intercepted token.","aliases":["CVE-2026-55513","GHSA-g4x6-jcvr-9m3g"],"modified":"2026-07-23T18:00:23.848180658Z","published":"2026-07-23T17:34:12Z","database_specific":{"review_status":"REVIEWED","url":"https://pkg.go.dev/vuln/GO-2026-5987"},"references":[{"type":"ADVISORY","url":"https://github.com/forgekeep/nebula-mesh/security/advisories/GHSA-g4x6-jcvr-9m3g"},{"type":"FIX","url":"https://github.com/forgekeep/nebula-mesh/commit/514006029e09f1991122b86a80e7b25970bcfa98"},{"type":"WEB","url":"https://github.com/forgekeep/nebula-mesh/releases/tag/v0.5.0"}],"affected":[{"package":{"name":"github.com/forgekeep/nebula-mesh","ecosystem":"Go","purl":"pkg:golang/github.com/forgekeep/nebula-mesh"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.4.0"},{"fixed":"0.5.0"}]}],"ecosystem_specific":{"imports":[{"path":"github.com/forgekeep/nebula-mesh/internal/web","symbols":["Web.ServeHTTP","Web.handleHostCreate"]},{"path":"github.com/forgekeep/nebula-mesh/internal/api","symbols":["Server.ServeHTTP","Server.tokenTTLFor"]},{"path":"github.com/forgekeep/nebula-mesh/internal/cli","symbols":["Serve"]}]},"database_specific":{"source":"https://vuln.go.dev/ID/GO-2026-5987.json"}},{"package":{"name":"github.com/juev/nebula-mesh","ecosystem":"Go","purl":"pkg:golang/github.com/juev/nebula-mesh"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.3.0"}]}],"ecosystem_specific":{"imports":[{"path":"github.com/juev/nebula-mesh/internal/web","symbols":["Web.ServeHTTP","Web.handleHostCreate"]},{"path":"github.com/juev/nebula-mesh/internal/api","symbols":["Server.ServeHTTP","Server.tokenTTLFor"]},{"symbols":["Serve"],"path":"github.com/juev/nebula-mesh/internal/cli"}]},"database_specific":{"source":"https://vuln.go.dev/ID/GO-2026-5987.json"}}],"schema_version":"1.7.5"}
