Summary
CVE-2026-25884 is a low-severity Out-of-bounds Read (CWE-125) vulnerability in Exiv2 Exiv2. Its CVSS base score is 2.7 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 23th 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 SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-25884 is an out-of-bounds read vulnerability (CWE-125) affecting Exiv2, a C++ library and command-line utility for reading, writing, deleting, and modifying Exif, IPTC, XMP, and ICC image metadata. The flaw resides in the CRW image parser and impacts all versions prior to 0.28.8. It carries a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H), indicating high severity due to potential impacts on confidentiality and availability.
The vulnerability can be exploited remotely by unauthenticated attackers with low complexity, requiring only user interaction such as processing a malicious CRW image file via the Exiv2 library or utility. Successful exploitation enables high-impact confidentiality violations, such as disclosure of sensitive memory contents, and high-impact availability disruptions, like application crashes or denial of service, without affecting integrity.
Mitigation is available through upgrading to Exiv2 version 0.28.8 or later, where the issue has been patched. Relevant resources include the fixing commit at https://github.com/Exiv2/exiv2/commit/cbba4d206512fe63e12d164fdd1881562f072a9d, the associated pull request at https://github.com/Exiv2/exiv2/pull/3462, and the security advisory at https://github.com/Exiv2/exiv2/security/advisories/GHSA-9mxq-4j5g-5wrp.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation directly finds out-of-bounds read flaws through static analysis, fuzzing, and dynamic bounds checks.
Secure engineering principles require bounds checking and memory-safe constructs that stop out-of-bounds reads from being introduced.
Process isolation confines the effects of an out-of-bounds read to the compromised process.
Input validation rejects malformed indices or lengths that would otherwise cause reads outside buffer bounds.

Secure-development practices such as bounds checking and memory-safe languages directly prevent out-of-bounds reads.
Vulnerability scanning and recording can discover instances of out-of-bounds reads after code is deployed.

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.
Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.
Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.
Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.
Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.
Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
