Summary

CVE-2026-76846 is a high-severity Insufficiently Protected Credentials (CWE-522) vulnerability. Its CVSS base score is 8.7 (High).

Operationally, ranked at the 21th 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 SC-28 (Protection of Information at Rest) and SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Vulnerability Data

Grav before 2.0.16 contains an incomplete default denylist in the Twig sandbox configuration that fails to block access to system configuration secrets. Attackers with page-edit permission can use config.get() or config.toArray() in Twig templates to retrieve sensitive values like system.cache.redis.password…

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Protection of information at rest requires encryption or equivalent safeguards for stored credentials.

Transmission confidentiality and integrity enforcement stops credentials from being sent in plaintext or without protection.

Authenticator management requires secure generation, storage, and distribution of credentials, directly stopping insecure methods.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.

blocks

A.5.10 only requires awareness, a topic-specific acceptable-use policy stating expected behaviours/monitoring, and procedures referencing other controls (e.g. access restrictions, marking, disposal); it performs none of the verb on CWE-522's insecure credential transmission/storage, which requires technical protections like encryption or secure channels that this governance clause does not supply.

blocks

A.5.17 mandates secure allocation, transmission, storage, hashing/encryption per 8.24, strong non-reusable passwords, immediate change of defaults/compromise, and no cleartext — directly stopping exploitation of insufficiently protected credentials with only a bounded remainder (e.g. non-password authenticators or post-storage exposure vectors outside its scope).

blocks

A.6.2 sets contractual terms, NDAs, and communicates responsibilities to personnel; it has no technical effect on how credentials are protected in transmission or storage and cannot stop exploitation of CWE-522

blocks

Regular reminders about password security and personal accountability make users less likely to store or transmit credentials in cleartext or other unprotected forms.

blocks

A.8.24's purpose, guidance (b,c), and key management mandate proper cryptography (algorithms, strength, protection of credentials in storage/transmission) per classification, which stops exploitation of insufficiently-protected credentials; remainder is bounded (e.g. non-cryptographic protections like hashing-only or non-crypto obfuscation per CWE-522 details).

blocks

A.8.5 mandates MFA, alternative strong methods, no cleartext transmission/storage of passwords, session termination, brute-force protection and secure log-on procedures that directly stop interception/retrieval of credentials even when they exist, leaving only a bounded remainder (e.g. non-password credentials or post-authentication storage outside log-on flows)

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-522, a class-level weakness. Rules are authored against its narrower children: CWE-260, CWE-523.
