Vulnerability Data

The WordPress Infinite Scroll – Ajax Load More plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 7.0.1 due to insufficient input sanitization and output escaping. This makes it possible…

for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation requires complete, allowlist-style checks that structurally eliminate reliance on incomplete XSS denylists.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles mandate robust sanitization and validation approaches that avoid incomplete denylist patterns.

Mitigating Controls (NIST CSF 2.0) AI

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 robust input validation and sanitization (e.g., allowlists) rather than incomplete denylists for XSS.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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

A.8.29 Security testing in development and acceptance mostly match

finds

Security testing can discover incomplete denylists, yet the control does not mandate their replacement.

A.8.25 Secure development life cycle partial match

prevents

Secure-SDLC processes encourage proper input/output handling, but do not specifically address denylist shortcomings.

A.8.26 Application security requirements partial match

prevents

Application-security requirements can mandate proper output encoding, but the control itself does not prescribe the technique.

A.8.28 Secure coding partial match

prevents

Secure-coding rules directly require allow-list or context-aware escaping instead of incomplete denylists for XSS.
