CVE-2026-43573
Published: 05 May 2026
Description
OpenClaw before 2026.4.10 contains a server-side request forgery policy bypass vulnerability in existing-session browser interaction routes. Attackers can bypass SSRF navigation guards to interact with or navigate to unauthorized targets without policy enforcement.
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Missing authorization for internal functions is mitigated by requiring all external access to traverse managed boundaries.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Security SummaryAI
CVE-2026-43573, published on 2026-05-05, affects OpenClaw versions before 2026.4.10. The vulnerability is a server-side request forgery (SSRF) policy bypass in existing-session browser interaction routes, allowing attackers to circumvent SSRF navigation guards and interact with or navigate to unauthorized targets without policy enforcement. It is linked to CWE-862 (Missing Authorization) and CWE-918 (Server-Side Request Forgery), with a CVSS v3.1 base score of 7.7 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).
Low-privileged users (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Exploitation changes scope (S:C) and enables high confidentiality impact (C:H), permitting access to sensitive or unauthorized internal resources through bypassed policy controls.
Mitigation is available in OpenClaw 2026.4.10. The fixing commit is at https://github.com/openclaw/openclaw/commit/daeb74920d5ad986cb600625180037e23221e93a, with advisories published at https://github.com/openclaw/openclaw/security/advisories/GHSA-527m-976r-jf79 and https://www.vulncheck.com/advisories/openclaw-ssrf-policy-bypass-in-existing-session-browser-interaction-routes.

MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
SSRF policy bypass in public-facing web application (OpenClaw) directly enables initial access via exploitation of a public-facing app vulnerability (CWE-918 + CWE-862).
