From 0.4.0 until 0.5.15, the @backstage/plugin-catalog-backend-module-bitbucket-server package is affected by inconsistent repository filtering in bitbucket server catalog event updates. Deployments using event-driven updates in the Bitbucket Server catalog provider may ingest catalog locations from repositories that are excluded by the provider's configured project, repository, or archived-repository filters. An authenticated Bitbucket Server user who can push to a filtered-out repository that remains readable by the configured Backstage integration can trigger a legitimate repository event. The affected event path may then add a Location for that repository even though scheduled discovery excludes it. This issue is fixed in version 0.5.15.","state":0,"publishedAt":"2026-10-06T20:16:12.035+00:00","modifiedAt":"2026-10-07T17:07:16.596+00:00","affected":[{"ecosystem":"Vendor product","name":"backstage","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"backstage\",\n                    \"product\": \"backstage\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.38.0, < 1.55.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"plugin-catalog-backend-module-bitbucket-server","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"@backstage\",\n                    \"product\": \"plugin-catalog-backend-module-bitbucket-server\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.4.0, < 0.5.15\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/backstage/backstage/security/advisories/GHSA-c36c-cf6r-ghgj","https://github.com/backstage/backstage/commit/989db63b6f87c8fc04d440f296ad89e10c79b363","https://github.com/backstage/backstage/releases/tag/v1.55.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106458","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106458","identifiers":["CVE-2026-106458"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
