Vulnerability Data

The Broken Link Notifier plugin for WordPress is vulnerable to CSV Injection in all versions up to, and including, 1.3.0 via broken links that are later exported. This makes it possible for authenticated attackers, with Contributor-level access and above, to…

embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

Mitigating Controls (NIST 800-53 r5) AI

SI-15 Information Output Filtering good match

Output filtering/validation directly stops unneutralized formula elements from being written into CSV files.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match

prevents

Secure SDLC practices directly require output neutralization for untrusted CSV content to block formula injection.

A.8.29 Security testing in development and acceptance mostly match

finds

Security testing in development can detect formula injection but does not itself implement the mitigation.

A.8.25 Secure development life cycle partial match

prevents

Secure SDLC mandates input validation and output encoding that directly prevents formula injection in CSV exports.

A.8.26 Application security requirements partial match

prevents

Application security requirements include rules for safe CSV generation and handling of untrusted data.

A.8.27 Secure system architecture and engineering principles partial match

prevents

Secure architecture principles encourage safe data export design but do not specifically address CSV formula neutralization.

A.8.28 Secure coding partial match

prevents

Secure coding standards explicitly require neutralization of special characters when writing CSV files.
