CVE-2026-31839 is a high-severity Improper Validation of Integrity Check Value (CWE-354) vulnerability in Striae Striae. Its CVSS base score is 8.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Supply Chain Compromise (T1195); ranked at the 2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

CVE-2026-31839 is a high-severity integrity bypass vulnerability (CVSS 8.2, CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N; CWE-354) affecting Striae, an open-source tool used as a firearms examiner's comparison companion. The issue resides in the digital confirmation workflow prior to version 3.0.0, where hash-only validation improperly trusted manifest hash fields. These fields could be modified alongside the package content, enabling tampered confirmation packages to pass integrity checks without detection.
A local attacker with low-complexity methods and no privileges can exploit this vulnerability by crafting a malicious confirmation package and tricking a user into processing it via the workflow (user interaction required). Successful exploitation changes scope to high, granting high confidentiality and integrity impacts, such as injecting falsified forensic data that appears legitimate, potentially undermining ballistic comparisons or evidence validation in firearms examinations.
The vulnerability is fixed in Striae version 3.0.0, as detailed in the project's GitHub release notes (https://github.com/striae-org/striae/releases/tag/v3.0.0) and security advisory (https://github.com/striae-org/striae/security/advisories/GHSA-mmf8-487q-p45m). Security practitioners should urge users to update to v3.0.0 or later and validate packages using enhanced integrity mechanisms beyond manifest hashes.

Mitigating Controls (NIST 800-53 r5) AI
Requires integrity verification tools that detect unauthorized changes when checksum validation is missing or flawed.
Mandates cryptographic mechanisms that include integrity protection, preventing improper checksum validation.
Requires protection of transmitted information integrity, directly mandating correct validation of integrity checks.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Requires cryptographic hashes and signatures that directly enforce integrity-check validation for data at rest.
Requires cryptographic hashes and signatures that directly enforce integrity-check validation for data in transit.
Mandates pre-acquisition integrity assessment, addressing only the initial portion of the weakness lifecycle.
Requires verification of backup integrity, covering validation only within recovery scenarios.
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.
Cryptographic controls mandate integrity mechanisms whose correct validation directly prevents CWE-354.
Secure coding standards require proper implementation and validation of checksums or MACs.
Security testing can detect missing integrity validation but does not itself implement the control.
Application security requirements include integrity checks on messages and data, mitigating improper validation.
Network security policies may require integrity protection on transit data, indirectly addressing the weakness.
