Description

Duplicate Advisory: OpenClaw: Windows media loaders accepted remote-host file URLs before local path validation

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-h3x4-hc5v-v2gm. This link is maintained to preserve external references.

Original Description

OpenClaw versions prior to commit b57b680 contain an approval bypass vulnerability due to inconsistent environment variable normalization between approval and execution paths, allowing attackers to inject attacker-controlled environment variables into execution without approval system validation. Attackers can exploit differing normalization logic to discard non-portable keys during approval processing while accepting them at execution time, bypassing operator review and potentially influencing runtime behavior including execution of attacker-controlled binaries.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. A user must actively cooperate. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity high, availability none.

Weakness class

GHSA-8h8f-7cxm-m38j is classified as CWE-184: Incomplete List of Disallowed Inputs. The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.

Affected software

GHSA-8h8f-7cxm-m38j is recorded against 1 package.
