Medium [CVE-2026-83530] Denial of Service via uncontrolled memory allocation
CVE-2026-83530Source published Source updated
A user could provide an expression whose string length is longer than the ParserExpressionSizeLimit() configured on the CEL environment, and a memory allocation would occur proportional to the size of the input before the limit would be checked / enforced. A flaw was found in cel-go. A user can trigger a Denial of Service (DoS) by submitting an expression that exceeds the configured parser expression size limit. Because memory is allocated proportional to the input length before the limit is validated, processing oversized inputs causes uncontrolled memory consumption.
