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-2026-53532 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-2026-53532/ (Markdown: https://insights.sbomify.com/CVE-2026-53532/index.md)","id":"CVE-2026-53532","markdown":"https://insights.sbomify.com/CVE-2026-53532/index.md","name":"CVE-2026-53532","record":{"aliases":["BELL-CVE-2026-53532","DEBIAN-CVE-2026-53532","ECHO-4fbe-495c-354e","GHSA-2f85-52wj-hc3c","MINI-pqvv-5fjr-cx57","ROOT-OS-DEBIAN-11-CVE-2026-53532","ROOT-OS-DEBIAN-12-CVE-2026-53532","ROOT-OS-DEBIAN-13-CVE-2026-53532","UBUNTU-CVE-2026-53532"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenEXR image library","requires_auth":"none","summary":"Attackers can cause a denial of service by providing a crafted EXR file that triggers an unhandled assertion abort in the HTJ2K decoder.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.12, a crafted HTJ2K-compressed EXR file causes an unconditional process abort in any application that calls exr_start_read() on untrusted input, resulting in denial of service. The crash is triggered by a QCD marker whose lower five bits are zero, which OpenEXR passes into the vendored OpenJPH library while constructing the codestream and evaluating its quantization delta parameters. OpenJPH uses an assertion rather than a recoverable error to validate those bits, so any invalid value calls abort() directly and cannot be intercepted by surrounding error handling, a problem compounded by OpenEXR wrapping only its internal HT header parser in error handling while leaving the later codestream read and construction calls unprotected. This issue has been resolved in version 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: Unhandled assert abort in HTJ2K decoder via crafted QCD marker (DoS)","id":"CVE-2026-53532","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"aiosmtplib: SMTP command injection via CR/LF in sender/recipient address","id":"CVE-2026-53533"},"packages":[],"prev":{"headline":"ratex-parser has unbounded parser recursion that leads to stack overflow (process abort)","id":"CVE-2026-53531"},"products":["openexr"],"published":"2026-08-24","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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-28","vendors":["AcademySoftwareFoundation"]},"summary":"Attackers can cause a denial of service by providing a crafted EXR file that triggers an unhandled assertion abort in the HTJ2K decoder.","url":"https://insights.sbomify.com/CVE-2026-53532/"}
