Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A crafted psd with an invalid color_mode bypasses normal validation when oiio:rawcolor or psd:rawdata is enabled. psdinput::setup() then uses the attacker-controlled value to index fixed color-mode tables, causing a global out-of-bounds read and potentially a bogus allocation, resulting in denial of service. The affected implementation is identified by src/psd.imageio/psdinput.cpp, PSDInput::validate_header(), PSDInput::setup(), oiio:RawColor, psd:RawData, color_mode, and mode_channel_count, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1."}],"source":{"advisory":"GHSA-3c8w-9xvm-r6gf","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/user-attachments/files/29539076/poc.zip","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-24T20:56:37.753363Z","id":"CVE-2026-63635","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-24T20:56:40.284Z"}}]}}
