{"identifier":"CVE-2026-112257","cve":{"id":"CVE-2026-112257","description":"A flaw was found in GIMP. The PSD thumbnail resource loader performs a BGR-to-RGB channel swap with a fixed 3-byte stride and does not verify that the JPEG thumbnail is RGB. A crafted grayscale PSD thumbnail can cause a heap out-of-bounds read and write in the plug-in process, leading to a crash and potentially arbitrary code execution when the victim browses or opens the file.","published":"2026-10-19T22:17:05.420000+00:00","modified":"2026-10-20T15:17:13.717000+00:00","status":"Awaiting Analysis","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cvss_version":"3.1","affected":[],"weaknesses":["CWE-121"],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-112257","source":"secalert@redhat.com"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2555574","source":"secalert@redhat.com"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"secalert@redhat.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-20T14:47:14.486852Z","id":"CVE-2026-112257","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:23:52.640933+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00167,"percentile":0.05957,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"access.redhat.com","source_url":"https://access.redhat.com/security/cve/CVE-2026-112257","investigate_url":"https://investigate.aeglixmind.com/#access.redhat.com"},{"domain":"bugzilla.redhat.com","source_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2555574","investigate_url":"https://investigate.aeglixmind.com/#bugzilla.redhat.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-112257","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-112257","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-112257","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
