By default, if Bash is run with its effective UID not equal to its real UID, it will drop privileges by setting its effective UID to its real UID. However, it does so incorrectly. On Linux and other systems that support \"saved UID\" functionality, the saved UID is not dropped. An attacker with command execution in the shell can use \"enable -f\" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges. However, binaries running with an effective UID of 0 are unaffected.","state":0,"publishedAt":"2019-11-28T00:27:51+00:00","modifiedAt":"2026-10-14T06:54:52.201+00:00","affected":[{"ecosystem":"Vendor product","name":"n/a","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"n/a\",\n                    \"vendor\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"n/a\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://lists.apache.org/thread.html/rf9fa47ab66495c78bb4120b0754dd9531ca2ff0430f6685ac9b07772%40%3Cdev.mina.apache.org%3E","https://security.gentoo.org/glsa/202105-34","https://www.oracle.com/security-alerts/cpuapr2022.html","https://www.youtube.com/watch?v=-wGtxJ8opa8","https://github.com/bminor/bash/commit/951bdaad7a18cc0dc1036bba86b18b90874d39ff","http://packetstormsecurity.com/files/155498/Bash-5.0-Patch-11-Privilege-Escalation.html","https://security.netapp.com/advisory/ntap-20200430-0003/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2019-18276","license":"CVE Program Terms of Use","key":"cve-program:CVE-2019-18276","identifiers":["CVE-2019-18276"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
