ImageMagick before 7.1.2-27 contains a memory leak vulnerability in the magick command-line interface when invalid options are provided. (CVE-2026-66011)
ImageMagick versions prior to 7.1.2-27 have a memory leak vulnerability in the magick command-line interface triggered by invalid options. This flaw allows attackers to cause memory exhaustion by repeatedly supplying malformed command-line arguments, potentially impacting system availability. The vulnerability has a moderate severity rating with a CVSS score of 3.3. No known exploits are reported in the wild. A fix is available in version 7.1.2-27.
AI Analysis
Technical Summary
CVE-2026-66011 describes a memory leak vulnerability in ImageMagick's magick command-line interface in versions before 7.1.2-27. When invalid options are provided, the program fails to properly release allocated memory, leading to resource exhaustion if exploited repeatedly. This vulnerability is categorized under CWE-401 (Improper Release of Memory). The CVSS 3.1 base score is 3.3 (medium), reflecting low impact on confidentiality and integrity but a potential availability impact due to memory exhaustion. There are no known active exploits. The vulnerability is fixed in ImageMagick version 7.1.2-27.
Potential Impact
The vulnerability can lead to memory exhaustion on affected systems by processing malformed command-line arguments repeatedly, potentially causing denial of service. There is no impact on confidentiality or integrity. No known exploits in the wild have been reported.
Mitigation Recommendations
Upgrade ImageMagick to version 7.1.2-27 or later, where this memory leak vulnerability has been fixed. Until then, avoid supplying invalid or malformed command-line options to the magick interface to reduce risk.
