{"id":"CVE-2026-44596","summary":"Yamcs: No Rate Limiting on Authentication Endpoint","details":"Yamcs is a mission control framework. Prior to 5.12.7, the authentication endpoint POST /auth/token in yamcs-core, handled by yamcs-core/src/main/java/org/yamcs/http/auth/AuthHandler.java, lacked any rate limiting, account lockout, or failed-attempt throttling, so an unauthenticated remote attacker could perform unlimited password-guessing attempts against any user account, significantly increasing the risk of successful brute-force attacks. This issue is fixed in versions 5.12.7 and 5.13.0.","aliases":["GHSA-w5r6-mcgq-7pq4"],"modified":"2026-07-19T03:46:51.561461404Z","published":"2026-07-16T16:04:11.794Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-307"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44596.json"},"references":[{"type":"WEB","url":"https://github.com/yamcs/yamcs/releases/tag/yamcs-5.12.7"},{"type":"WEB","url":"https://github.com/yamcs/yamcs/releases/tag/yamcs-5.13.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44596.json"},{"type":"ADVISORY","url":"https://github.com/yamcs/yamcs/security/advisories/GHSA-w5r6-mcgq-7pq4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44596"},{"type":"FIX","url":"https://github.com/yamcs/yamcs/commit/309218c651680f79df11a8d0f8628f7033f98a83"},{"type":"FIX","url":"https://github.com/yamcs/yamcs/commit/64392df531fbcbc65f19ee5724c4c23d289f49fc"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/yamcs/yamcs","events":[{"introduced":"0"},{"fixed":"1262da4e2ffe7538d9ae4d6e7b22a345b3e1a2bb"},{"fixed":"309218c651680f79df11a8d0f8628f7033f98a83"},{"fixed":"64392df531fbcbc65f19ee5724c4c23d289f49fc"},{"fixed":"8bf5af6fe227bbf8ead15e60644b7ddbf345d623"}],"database_specific":{"cpe":"cpe:2.3:a:spaceapplications:yamcs:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"5.12.7"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["yamcs-5.12.6","yamcs-5.12.5","yamcs-5.12.4","yamcs-5.12.3","yamcs-5.12.2","yamcs-5.12.1","yamcs-5.12.0","yamcs-5.11.7","yamcs-5.9.8","yamcs-5.11.6","yamcs-5.11.5","yamcs-5.11.4","yamcs-5.10.9","yamcs-5.11.3","yamcs-5.11.2","yamcs-5.11.1","yamcs-5.11.0","yamcs-5.10.8","yamcs-5.10.7","yamcs-5.10.6","yamcs-5.10.5","yamcs-5.10.4","yamcs-5.10.3","yamcs-5.10.2","yamcs-5.10.1","yamcs-5.10.0","yamcs-5.9.7","yamcs-5.9.6","yamcs-5.9.5","yamcs-5.9.4","yamcs-5.9.3","yamcs-5.9.2","yamcs-5.9.1","yamcs-5.9.0","yamcs-5.8.8","yamcs-5.8.7","yamcs-5.8.6","yamcs-5.8.5","yamcs-5.8.4","yamcs-5.8.3","yamcs-5.8.2","yamcs-5.8.0","yamcs-5.8.1","yamcs-5.7.10","yamcs-5.7.9","yamcs-5.7.8","yamcs-5.7.7","yamcs-5.7.6","yamcs-5.7.5","yamcs-5.7.4","yamcs-5.7.3","yamcs-5.7.2","yamcs-5.7.1","yamcs-5.7.0","yamcs-5.6.2","yamcs-5.5.7","yamcs-5.6.1","yamcs-5.6.0","yamcs-5.5.6","before-removing-cfdp-half-implemented-features","yamcs-5.5.5","yamcs-5.5.4","yamcs-5.5.3","yamcs-5.5.2","yamcs-5.5.1","yamcs-5.5.0","yamcs-5.3.5","yamcs-5.4.3","yamcs-5.4.2","yamcs-5.4.1","yamcs-5.4.0","yamcs-5.2.0","yamcs-5.3.4","yamcs-5.3.3","yamcs-5.3.2","yamcs-5.3.1","yamcs-5.3.0","yamcs-5.1.3","yamcs-5.1.2","yamcs-5.1.1","yamcs-5.1.0","yamcs-5.0.1","yamcs-5.0.0","yamcs-4.10.9","yamcs-4.10.8","yamcs-4.10.7","yamcs-4.10.6","yamcs-4.10.5","yamcs-4.10.4","yamcs-4.10.3","yamcs-4.10.2","yamcs-4.10.1","yamcs-4.10.0","yamcs-4.9.5","yamcs-4.9.4","yamcs-4.9.3","yamcs-4.9.2","yamcs-4.9.1","yamcs-4.9.0","yamcs-4.8.1","yamcs-4.8.0","yamcs-4.7.3","yamcs-4.7.2","yamcs-4.7.1","yamcs-4.7","yamcs-4.4.2","yamcs-4.4.1","yamcs-4.4.0","yamcs-4.3.1","yamcs-4.3.0","yamcs-4.2.2","yamcs-4.2.1","yamcs-4.2.0","yamcs-4.1.2","yamcs-4.1.1","yamcs-4.0.1","yamcs-3.4.0","yamcs-3.3.0","yamcs-3.2.2","yamcs-3.2.1","yamcs-3.2.0","yamcs-3.1.2","yamcs-3.1.1","yamcs-3.1.0","yamcs-3.0.0","yamcs-0.30.0","v0.29.4","v0.29.3-20160608","v0.29.3","v0.29.1","v0.29.1-20160127","v0.29.1-20160119","v0.29.1-20151214","v0.29.0","v0.28.0","v0.28.0-20150903","v0.28.0-20150902-2","v0.28.0-20150902","v0.28.0-20150901","v0.28.0-20150828","v0.28.0-20150827","v0.28.0-20150826","v0.28.0-20150825","v0.28.0-20150824","v0.28.0-20150820","v0.28.0-20150817","v0.28.0-20150811","v0.26.1","v0.26.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44596.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
