No releases were published with these tags; a project was exposed only if it defined a git-based dependency referencing one of the affected tags (for example, parse-server#4.9.3). The code behind the tags was not reviewed or approved, and although no malicious code was identified, the introduction of security vulnerabilities could not be ruled out.","published":"2026-06-25T22:16:58.373Z","modified":"2026-08-07T16:57:49.877496Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"4.5.2"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"4.10.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-593v-wcqx-hq2w"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/parse-server-arbitrary-code-execution-via-malicious-version-tags"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T16:57:49.877496Z"}}
