CVE-2026-27287: Out-of-bounds Read (CWE-125) in Adobe InCopy
Adobe InCopy versions 20. 5. 2, 21. 2, and earlier contain an out-of-bounds read vulnerability when parsing specially crafted files. This flaw can lead to reading beyond allocated memory boundaries, potentially allowing an attacker to execute code with the privileges of the current user. Exploitation requires user interaction, specifically opening a malicious file. The vulnerability has a high severity rating with a CVSS score of 7. 8. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
CVE-2026-27287 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe InCopy versions 20.5.2, 21.2, and earlier. The vulnerability occurs during the parsing of crafted files, causing the application to read past the end of an allocated memory structure. This memory corruption can be leveraged by an attacker to execute arbitrary code in the context of the current user. Exploitation requires that the victim opens a maliciously crafted file, implying user interaction is necessary. The CVSS 3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. No patch or official remediation level has been published by Adobe as of the data provided.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary code with the privileges of the current user, potentially leading to full compromise of the user's environment within the scope of Adobe InCopy. The vulnerability affects confidentiality, integrity, and availability of the affected system. However, exploitation requires user interaction by opening a malicious file. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution when opening files from untrusted sources. No official mitigation or temporary fix has been provided by Adobe at this time.
