Summary

CVE-2026-29177 is a low-severity Cross-site Scripting (CWE-79) vulnerability in Craftcms Craft Commerce. Its CVSS base score is 1.9 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 12th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-15 (Information Output Filtering) — see the control section below for these in your framework.

Vulnerability Data

Craft Commerce is an ecommerce platform for Craft CMS. Prior to 4.10.2 and 5.5.3, a Stored Cross-Site Scripting (XSS) vulnerability exists in the Craft Commerce Order details. Malicious JavaScript can be injected via the Shipping Method Name, Order Reference, or…

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly blocks unsanitized user-supplied values (Shipping Method Name, Order Reference, Site Name) from being persisted and later rendered as executable script in the order slideout.

prevent

Filters outgoing order-detail content before display, removing or encoding script payloads that were stored via the vulnerable fields.

detect

Integrity verification of rendered order pages can flag unexpected script insertion after the stored XSS payload has been saved.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).

PR.PS-02 partial match
prevents

Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).

detects

Secure-coding testing and automated code-analysis tools are applied to detect improper neutralization of script-related content during web-page generation.

prevents

Knowledge exchange on emerging attack techniques and patches reduces the likelihood that cross-site scripting flaws remain unaddressed in deployed applications.

prevents

Operational indicators of compromise for web-application attacks can be incorporated into WAF or input-filtering rules, lowering the likelihood that unsanitized data reaches the browser.

prevents

Requiring language-specific secure-coding standards and automated scanning during the SDLC catches missing output encoding or improper neutralization of untrusted data before the software reaches production.

prevents

Secure-coding standards, SAST scans and removal of insecure code samples together eliminate the failure to neutralize script content that produces cross-site scripting flaws.

none

Webpage malware scanning and block-listing of known malicious sites reduce the likelihood that reflected or stored script payloads reach a user’s browser.
