An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-26623 exists.\n\nAffected packages and fixed versions:\n- exiv2 (PyPI): affected from 0.28.0; fixed in 0.28.5\n- exiv2 (PyPI): affected from 0.28.0; fixed in 0.28.5\n- Exiv2 (PyPI): affected from 0.28.0; fixed in 0.28.5\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-26623/ (Markdown: https://insights.sbomify.com/CVE-2025-26623/index.md)","id":"CVE-2025-26623","markdown":"https://insights.sbomify.com/CVE-2025-26623/index.md","name":"CVE-2025-26623","record":{"aliases":["ALSA-2025:7457","AZL-56946","AZL-57071","DEBIAN-CVE-2025-26623","GHSA-38h4-fx85-qcx7","OESA-2025-1197","OESA-2025-1198","PYSEC-2026-1353","RHSA-2025:7457","RLSA-2025:7457"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Image metadata library","requires_auth":"none","summary":"Attacker can execute code by tricking users into writing metadata to a crafted image file using the Exiv2 library.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"exiv2","vendor":"exiv2"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A heap buffer overflow was found in Exiv2 versions v0.28.0 to v0.28.4. Versions prior to v0.28.0, such as v0.27.7, are **not** affected. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The heap overflow is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to gain code execution, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `fixiso`. The bug is fixed in version v0.28.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.","ecosystems":["AlmaLinux:10","PyPI","Red Hat:enterprise_linux:10.0","Rocky
