2 techniques across 2 tactics: Execution, Privilege Escalation

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Impact

Memory corruption that can be exploited for arbitrary code execution, information disclosure, or denial of service. With a CVSS score of 8.1 (HIGH), this represents a significant risk.

Exploit ScenarioDerived

An attacker triggers a specific sequence of operations that causes the application to free a memory block and then reference it again, potentially executing attacker-controlled data.

AnalysisAIv1 – Mar 13, 2026

A heap-use-after free in the PdfTokenizer::ReadDictionary function of podofo v0.10.0 to v0.10.5 allows attackers to cause a Denial of Service (DoS) by supplying a crafted PDF file. NOTE: this is disputed by the Supplier because there is no available file to reproduce the issue.

Executive ViewAI

Why It Matters

CVE-2025-46205 presents notable security risk, a use-after-free vulnerability rated CVSS 8.1. Successful exploitation could significantly impact the confidentiality, integrity, or availability of affected systems. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates when available and consider compensating controls in the interim.

Business Impact: High
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.

Attack Technique

Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
