CVE-2026-25797

The ps encoders, responsible for writing PostScript files, fails to sanitize the input before writing it into the PostScript header. An attacker can provide a malicious file and inject arbitrary PostScript code. When the resulting file is processed by a printer or a viewer (like Ghostscript), the injected code is interpreted and executed.

The html encoder does not properly escape strings that are written to in the html document. An attacker can provide a malicious file and injection arbitrary html code.

Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.

CVE-2026-25797 has a CVSS score of 5.7 (Medium). The vector is requires local access, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (14.10.3); upgrading removes the vulnerable code path.

5. Is CVE-2026-25797 exploitable, and should I be worried? Whether CVE-2026-25797 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-25797 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
