Security readout for executives and security teams
Plain-English summary
CVE-2024-28699 is reported as a high-severity buffer overflow in pdf2json v0.70. A local, low-privileged attacker could potentially run code with impacts to confidentiality, integrity, and availability. The sources do not identify a fixed version or broad affected-product mapping.
Executive priority
Treat as a focused high-priority dependency risk, not an internet-wide emergency. Prioritize environments where pdf2json handles untrusted or user-supplied PDFs, especially shared servers and automated conversion pipelines.
Technical view
The CVE describes a buffer overflow reachable through GString::copy() and ImgOutputDev::ImgOutputDev in pdf2json v0.70. CVSS 3.1 is 7.8 with local access, low complexity, low privileges, no user interaction, unchanged scope, and high CIA impact.
Likely exposure
Exposure is most likely where pdf2json v0.70 is installed or bundled in local PDF conversion workflows. The CVE metadata lists affected vendor/product as n/a, so dependency and container inventory are needed.
Exploitation context
The source bundle does not show CISA KEV listing or cited active exploitation. The attack vector is local, requiring low privileges, so risk depends on who can access systems running pdf2json and what PDFs they process.
Researcher notes
Evidence is incomplete: affected CPEs are absent and no patch version is named in the supplied sources. The CWE entry is CWE-94, while the description characterizes a buffer overflow. Validate against upstream issue details before assigning remediation SLAs.
Mitigation direction
- Inventory systems and applications using pdf2json v0.70.
- Check the vendor repository and issue for fixed-version guidance.
- Avoid processing untrusted PDFs with pdf2json v0.70 until clarified.
- Run PDF conversion under least privilege and sandboxing.
- Monitor CVE and vendor references for remediation updates.
Validation and detection
- Search source, lockfiles, containers, and hosts for pdf2json v0.70.
- Confirm whether production workflows invoke pdf2json on PDF inputs.
- Review the GitHub issue for maintainer-confirmed remediation status.
- Check whether local users can execute affected conversion paths.
- Verify compensating sandboxing and privilege boundaries around PDF parsing.

CWE-94: Code execution behavior lookup
Code execution and unsafe deserialization weaknesses often justify reviewing execution behavior and process telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
