Description
cel-rust is a Common Expression Language interpreter written in Rust. Starting in version 0.10.0 and prior to version 0.11.4, parsing certain malformed CEL expressions can cause the parser to panic, terminating the process. When the crate is used to evaluate untrusted expressions (e.g., user-supplied input over an API), an attacker can send crafted input to trigger a denial of service (DoS). Version 0.11.4 fixes the issue.

Executive Summary

This vulnerability exists in the cel-rust Common Expression Language interpreter versions from 0.10.0 up to but not including 0.11.4. When parsing certain malformed CEL expressions, the parser can panic and terminate the process. This means that if an attacker sends specially crafted input expressions, they can cause the application using cel-rust to crash.

Impact Analysis

The vulnerability can be exploited by an attacker to cause a denial of service (DoS) by crashing the process that uses cel-rust to evaluate expressions. This is particularly impactful when the crate evaluates untrusted or user-supplied input, such as over an API, potentially making the service unavailable.

Mitigation Strategies

Upgrade the cel-rust crate to version 0.11.4 or later, as this version fixes the vulnerability that causes the parser to panic and terminate the process when parsing certain malformed CEL expressions.
