CVE-2023-26155
CWE-78Published: October 14, 2023· Updated: Jun 17, 2026
Official Description
All versions of the package node-qpdf are vulnerable to Command Injection such that the package-exported method encrypt() fails to sanitize its parameter input, which later flows into a sensitive command execution API. As a result, attackers may inject malicious commands once they can specify the input pdf file path.
Risk Analysis
The node-qpdf package is vulnerable to command injection because the encrypt method fails to sanitize input parameters. This critical flaw allows attackers to execute arbitrary commands, resulting in a 9.8 CVSS score.
No public exploit is known, and it is not in the KEV catalog. The vulnerability is remotely exploitable with low complexity.
Update the node-qpdf package to a version that properly sanitizes input parameters.
Technical Analysis
CVE-2023-26155 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
