Summary

CVE-2026-35644 is a high-severity Cleartext Storage of Sensitive Information (CWE-312) vulnerability in Openclaw Openclaw. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and SC-28 (Protection of Information at Rest) — see the control section below for these in your framework.

Vulnerability Data

OpenClaw before 2026.3.22 contains an information disclosure vulnerability that allows attackers with operator.read scope to expose credentials embedded in channel baseUrl and httpUrl fields. Attackers can access gateway snapshots via config.get and channels.status endpoints to retrieve sensitive authentication information from…

Mitigating Controls (NIST 800-53 r5) AI

prevent

Restricts the operator.read scope so it cannot retrieve channel baseUrl/httpUrl fields containing embedded credentials.

prevent

Requires protection of sensitive authentication data at rest instead of allowing cleartext storage inside URL userinfo components.

prevent

Enforces access-control decisions on config.get and channels.status endpoints to block exposure of credential-bearing URLs.

PR.DS-01 full match
prevents

Encryption and cryptographic controls for data-at-rest directly prevent cleartext storage of sensitive information.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

mitigates

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

mitigates

Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.

A.8.11 Data masking partial match
mitigates

Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.

detects

When clear-text sensitive data is detected leaving controlled storage, the control can block the transfer, thereby limiting the exposure that would result from unencrypted storage on external media or cloud services.

mitigates

By insisting that any retained test copies be stored securely and only for testing, the control reduces the likelihood that clear-text operational data will persist on disk or in backups.
