{"apiVersion":"1.0","identifier":"CVE-2026-73055","description":"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.","publishedAt":"2026-08-15T22:16:55","lastModifiedAt":"2026-08-26T16:57:52","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73055","cvssScore":4.8,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","epssProbability":0.00207,"riskScore":0.49,"affectedProduct":"shescape","affectedVersions":"<2.1.15,>=3.0.0,<3.0.2","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73055","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73055","en":"https://www.redsauce.net/en/cves/CVE-2026-73055","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73055","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73055","de":"https://www.redsauce.net/de/cves/CVE-2026-73055","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73055","el":"https://www.redsauce.net/el/cves/CVE-2026-73055"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73055"}}
