## Technical details

An out-of-bounds read vulnerability (CWE-125) exists in Adobe InDesign Desktop versions 21.3, 20.5.3 and earlier. The flaw occurs when the application reads data past the end of the intended buffer while processing a file. An attacker can exploit this by delivering a malicious file to a user; once opened, the vulnerability allows the attacker to read sensitive information from the process memory. The attack vector is local and requires user interaction (UI:R), with a high impact on confidentiality but no direct impact on integrity or availability. Adobe has addressed this in security bulletin APSB26-58.
