AI Analysis
Technical Summary
CVE-2026-51808 describes a buffer overflow vulnerability in OpenHTJ2K versions 0.18.4 and before. The vulnerability affects the openhtj2k_decoder_impl class, specifically the invoke, invoke_line_based, invoke_line_based_stream, and invoke_line_based_predecoded functions in source/core/interface/decoder.cpp. Exploitation could lead to arbitrary code execution. No CVSS score or vendor advisory is available, and no patch or remediation level has been confirmed.
Potential Impact
Successful exploitation of this buffer overflow could allow an attacker to execute arbitrary code within the context of the affected application. This may lead to compromise of the system running the vulnerable OpenHTJ2K decoder. There are no known exploits in the wild at this time.
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 processing untrusted data with affected versions of OpenHTJ2K.
