Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45696 exists.\n\nAffected product: Openexr 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-2026-45696/ (Markdown: https://insights.sbomify.com/CVE-2026-45696/index.md)","id":"CVE-2026-45696","markdown":"https://insights.sbomify.com/CVE-2026-45696/index.md","name":"CVE-2026-45696","record":{"aliases":["BELL-CVE-2026-45696","DEBIAN-CVE-2026-45696","GHSA-gjpj-qv64-vwhf","JLSEC-2026-813","UBUNTU-CVE-2026-45696"],"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":"low_privilege","summary":"A heap buffer over-read in the OpenEXR HTJ2K decoder allows attackers to cause a crash or leak memory by providing a crafted EXR file.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"openexr","vendor":"openexr"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"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 3.4.11, the HTJ2K (High-Throughput JPEG 2000) decoder, ht_undo_impl() in OpenEXRCore is vulnerable to a heap-buffer-overflow READ. The  ht_undo_imp function copies decoded pixels out of a per-line OpenJPH buffer using the EXR channel's declared width as the iteration count. The codestream embedded in the EXR chunk can declare different (smaller) tile/line dimensions than the EXR header advertises, but ht_undo_impl() does not validate this — it pulls width 32-bit samples from cur_line-\u003ei32[] without checking the OpenJPH line buffer's actual length. A crafted EXR file produces a 4-byte heap-buffer-overflow READ immediately after a buffer allocated by ojph::local::codestream::finalize_alloc(). The bug is reachable through the standard scanline-decode entry point used by every consumer of exr_decoding_run/Imf::checkOpenEXRFile, including thumbnailers, asset pipelines, and the exrcheck utility — i.e. any application that opens untrusted EXR files. The result is a deterministic crash (DoS) and potential adjacent-heap leak. This issue has been fixed in version 3.4.12.","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 HTJ2K decoder heap buffer over-read in ht_undo_impl() (DoS)","id":"CVE-2026-45696","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openexr:openexr","products":["openexr:openexr"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Formie: Pre-authenticated server-side template injection in Hidden fields","id":"CVE-2026-45697"},"packages":[],"prev":{"headline":"Kopia: Unauthenticated RCE via SSH ProxyCommand Injection when --insecure --without-password is used","id":"CVE-2026-45695"},"products":["openexr"],"published":"2026-06-18","related":[{"cvss_score":9.1,"headline":"OpenEXR Heap Overflow in Scanline Deep Data Parsing","id":"CVE-2023-5841","kev_date_added":null,"published":"2024-02-01"},{"cvss_score":8.8,"headline":"OpenEXR is Vulnerable to Integer overflow in ImageChannel::resize leads to heap OOB write via OpenEXRUtil public API","id":"CVE-2026-41142","kev_date_added":null,"published":"2026-05-07"},{"cvss_score":8.8,"headline":"OpenEXR: Out-of-bounds read in `IDManifest::init()` during prefix expansion","id":"CVE-2026-42216","kev_date_added":null,"published":"2026-05-07"},{"cvss_score":8.8,"headline":"OpenEXR invalid write","id":"CVE-2017-9111","kev_date_added":null,"published":"2017-05-21"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-9113","kev_date_added":null,"published":"2017-05-21"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-9115","kev_date_added":null,"published":"2017-05-21"},{"cvss_score":8.7,"headline":"OpenEXR: Heap information disclosure in PXR24 decompression via unchecked decompressed size (undo_pxr24_impl)","id":"CVE-2026-34543","kev_date_added":null,"published":"2026-04-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-07-15","vendors":["AcademySoftwareFoundation"]},"summary":"A heap buffer over-read in the OpenEXR HTJ2K decoder allows attackers to cause a crash or leak memory by providing a crafted EXR file.","url":"https://insights.sbomify.com/CVE-2026-45696/"}
