TIMELINE Aug 10 Reserved by VulnCheck Aug 15 Published (CNA: VulnCheck) Aug 31 RESCORED — CVE-2026-73055 (ericcornelissen shescape). CVSS 9.3 → 6.3 (NVD).
Shescape before 2.1.15 (and 3.0.0 before 3.0.2) fails to properly escape tilde (~) characters in assignment contexts on Unix systems where the shell is explicitly configured to "sh" or true and /bin/sh points to BusyBox. Using the escape and escapeAll APIs with untrusted input in an assignment prefixed to a command, an attacker can inject a tilde payload to disclose the user's home directory location and, depending on usage, alter the location on which a command operates.
