Percent-encoded NUL characters survive input sanitization and are subsequently converted to whitespace during command-line parsing, allowing injection of additional arguments to /usr/bin/man. An attacker can inject the -P option to select an attacker-controlled pager command. NOTE: this issue exists because of an incomplete fix for CVE-2023-46321.","id":"GHSA-9hxf-w2gf-j4wv","modified":"2026-11-05T06:34:37Z","published":"2026-11-05T06:34:37Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-123014"},{"type":"WEB","url":"https://gitlab.com/gnachman/iterm2/-/commit/314ba43920dbce08808c032e89966918090bdf8e"},{"type":"WEB","url":"https://gitlab.com/gnachman/iterm2/-/commit/f29420ae4d3e0f986ee24ea286885d32af58175a"},{"type":"WEB","url":"https://iterm2.com/downloads.html"}],"schema_version":"1.4.0","severity":[{"score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","type":"CVSS_V4"}]}
