Attackers can pre-plant symlinks at p10k-instant-prompt-output-<user>-<pid> in TMPDIR, guessing the victim's shell PID, so shell startup truncates and overwrites targeted files.","cvssScore":4.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:N","cwes":["CWE-59"],"vendors":[],"products":[],"references":[{"url":"https://github.com/romkatv/powerlevel10k","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/blob/v1.20.0/internal/p10k.zsh#L6445-L6452","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/commit/7ddd1b2715c3844275214347a3572ac1fdd6dc39","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/issues/2972","tags":[]},{"url":"https://www.vulncheck.com/advisories/powerlevel10k-before-1.20.19-symlink-following-via-instant-prompt-temporary-file","tags":[]}],"exploitRefs":[{"url":"https://github.com/romkatv/powerlevel10k","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/blob/v1.20.0/internal/p10k.zsh#L6445-L6452","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/commit/7ddd1b2715c3844275214347a3572ac1fdd6dc39","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/issues/2972","tags":[]}],"hasPoc":true,"ai":null}
