Received Received - Intake
SHA-1 Collision Enables Cache Poisoning in OpenClaw Sandbox

Publication date: 2026-03-05

Last updated on: 2026-03-17

Assigner: VulnCheck

Description
OpenClaw versions prior to 2026.2.15 use SHA-1 to hash sandbox identifier cache keys for Docker and browser sandbox configurations, which is deprecated and vulnerable to collision attacks. An attacker can exploit SHA-1 collisions to cause cache poisoning, allowing one sandbox configuration to be misinterpreted as another and enabling unsafe sandbox state reuse.

Executive Summary

This vulnerability affects OpenClaw versions prior to 2026.2.15, where SHA-1 is used to hash sandbox identifier cache keys for Docker and browser sandbox configurations.

SHA-1 is a deprecated hashing algorithm that is vulnerable to collision attacks, meaning an attacker can create two different inputs that produce the same hash output.

An attacker can exploit these SHA-1 collisions to poison the cache, causing one sandbox configuration to be mistaken for another, which can lead to unsafe reuse of sandbox states.

Impact Analysis

The impact of this vulnerability is that an attacker can cause cache poisoning by exploiting SHA-1 collisions.

This can result in one sandbox configuration being misinterpreted as another, potentially allowing unsafe sandbox state reuse.

Such unsafe reuse could lead to security risks, including unauthorized access or execution within sandboxed environments.
