From version 3.4.0 to before version 3.4.8, sensitive information from heap memory may be leaked through the decoded pixel data (information disclosure). This occurs under default settings; simply reading a malicious EXR file is sufficient to trigger the issue, without any user interaction. This issue has been patched in version 3.4.8.","published_at":"2026-04-01T20:56:18.776000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":8.7,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-908"],"nvd_references":["https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-vc68-257w-m432","https://github.com/AcademySoftwareFoundation/openexr/commit/5f6d0aaa9e43802917af7db90f181e88e083d3b8","https://github.com/AcademySoftwareFoundation/openexr/releases/tag/v3.4.8"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:59.294327Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"academysoftwarefoundation","vendor_name":"AcademySoftwareFoundation","product_slug":"openexr","product_name":"openexr","version_start":">= 3.4.0, < 3.4.8","version_start_inclusive":true,"version_end":">= 3.4.0, < 3.4.8","version_end_inclusive":true,"cpe23_uri":"cve5:academysoftwarefoundation:openexr:>= 3.4.0, < 3.4.8:>= 3.4.0, < 3.4.8"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-vc68-257w-m432","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/AcademySoftwareFoundation/openexr/commit/5f6d0aaa9e43802917af7db90f181e88e083d3b8","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/AcademySoftwareFoundation/openexr/releases/tag/v3.4.8","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-04-01T20:56:18.776000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:53:26.161903Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:26.161903Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:26.161903Z","label":"CVSS score revised","source":"cvelistv5"}]}
