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-2026-59189 exists.\n\nAffected product: AcademySoftwareFoundation openexr. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-59189/ (Markdown: https://insights.sbomify.com/CVE-2026-59189/index.md)","id":"CVE-2026-59189","markdown":"https://insights.sbomify.com/CVE-2026-59189/index.md","name":"CVE-2026-59189","record":{"aliases":["AZL-97637","BELL-CVE-2026-59189","DEBIAN-CVE-2026-59189","ECHO-ec93-6da5-dcb2","GHSA-hwmv-39v6-739m","MINI-56hf-r542-h779","ROOT-OS-DEBIAN-11-CVE-2026-59189","ROOT-OS-DEBIAN-12-CVE-2026-59189","ROOT-OS-DEBIAN-13-CVE-2026-59189","UBUNTU-CVE-2026-59189"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenEXR image library","requires_auth":"none","summary":"An out-of-bounds read in OpenEXRUtil allows attackers to cause crashes or disclose information via crafted deep images with non-zero dataWindow origins.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In OpenEXRUtil versions 3.3.0 through 3.3.12 and 3.4.0 through 3.4.12, the documented TypedDeepImageChannel\u003cT\u003e::row() API can return an out-of-bounds pointer when a deep image has a non-zero dataWindow origin, resulting in a heap out-of-bounds read and crash, with potential information disclosure under a controlled heap layout. The flaw arises because ImfDeepImageChannel uses two conflicting coordinate models: at(x, y) uses absolute coordinates (with _base offset by dataWindow.min), while row(r) is documented as 0-based logical access. For a non-zero dataWindow.min, row(0) therefore points outside the _sampleListPointers allocation instead of at the first logical row. This issue is fixed in versions 3.3.13 and 3.4.13.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"OpenEXR: Out-of-bounds read in DeepImageChannel::row() for non-zero dataWindow origin","id":"CVE-2026-59189","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Grav Admin Plugin — IDOR Privilege Escalation via saveUser()","id":"CVE-2026-59190"},"packages":[],"prev":{"headline":"Part-DB: SVG Sanitization Bypass via Extension Spoofing Leads to Stored XSS in Attachment Viewer","id":"CVE-2026-59188"},"products":["openexr"],"published":"2026-08-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-25","vendors":["AcademySoftwareFoundation"]},"summary":"An out-of-bounds read in OpenEXRUtil allows attackers to cause crashes or disclose information via crafted deep images with non-zero dataWindow origins.","url":"https://insights.sbomify.com/CVE-2026-59189/"}
