Exploitation evidence

Disclosed: evidence found.
CVE published 13 May 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Red Hat has released an official security update that addresses this vulnerability. Users of affected Red Hat Enterprise Linux 10 versions should apply the provided patches as detailed in Red Hat Advisory RHSA-2025:7457 and the update instructions at https://access.redhat.com/articles/11258. Applying these updates mitigates the vulnerability. No additional mitigation steps are indicated by the vendor.

Description

Exiv2 is a C++ library to access image metadata, supporting read and write access to the Exif, IPTC and XMP metadata, Exif MakerNote support, extract and delete methods for Exif thumbnails, classes to access Ifd, and support for various image formats. Security Fix(es): * exiv2: Use After Free in Exiv2 (CVE-2025-26623) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

The use-after-free vulnerability in Exiv2 could allow an attacker to cause memory corruption, which might lead to application crashes or potentially arbitrary code execution if exploited. However, no known exploits are reported in the wild. The impact is considered moderate by Red Hat Product Security.

Summary

Exiv2 is a C++ library used for reading and writing image metadata. A use-after-free vulnerability (CWE-416) exists in Exiv2, identified as CVE-2025-26623. This vulnerability could potentially lead to memory corruption issues. Red Hat has released security updates for Red Hat Enterprise Linux 10 and its variants to fix this issue. The advisory references Red Hat Security Advisory RHSA-2025:7457 for detailed patch information. No CVSS score is provided, but Red Hat rates the impact as moderate.

CWE-416Use After Free (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #7
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Architecture and Design · Language Selection
Choose a language that provides automatic memory management.
Implementation · Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
