Last modified

CVE-2026-27524 is a low-severity vulnerability rated 2.3/10 on the CVSS scale. OpenClaw versions prior to 2026.2.21 accept prototype-reserved keys in runtime /debug set override object values, allowing prototype pollution attacks. Authorized /debug set callers can inject __proto__, constructor, or prototype keys to manipulate object prototypes and bypass command gate restrictions.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.

Description

OpenClaw versions prior to 2026.2.21 accept prototype-reserved keys in runtime /debug set override object values, allowing prototype pollution attacks.
