Exploitation Conditions

Requires an authenticated account with the WooCommerce 'Shop Manager' role (PR:H) on a WordPress site running the Astra theme at version 4.13.12 or earlier; the presence of the Shop Manager role further implies WooCommerce must be installed and active. Exploitation is network-reachable with low complexity and no user interaction needed to inject (UI:N), but the high privilege requirement - a trusted store-management account - is the primary limiting factor, confining realistic abuse to malicious insiders or attackers who have already compromised such an account. Impact is limited to integrity (content/markup injection); no confidentiality or availability impact.

Impact

This is a low-priority issue despite affecting a very widely deployed product. The CVSS 3.1 base score is 2.7 (Low), driven by PR:H (requires an authenticated high-privilege account - a WordPress Shop Manager role, which implies WooCommerce is installed) and an impact limited to I:L with no confidentiality or availability impact (C:N/A:N). CWE-80 (basic XSS via HTML tag injection) combined with the vector points to stored/reflected content injection that a Shop Manager could plant, but the attacker already needs a trusted, privileged account, sharply limiting real-world abuse to insider or post-compromise scenarios. No EPSS score, KEV listing, or public POC was provided, so exploitation is 'no public exploit identified at time of analysis.' There is no conflict between the CVSS vector (AV:N/AC:L/PR:H/UI:N) and the description - both agree on an authenticated, network-reachable, low-integrity content-injection flaw. The only nuance is that the Patchstack tag labels this 'XSS' while the title says 'Content Injection'; CWE-80 spans both and the practical effect is script/markup injection, so the risk is a self- or peer-targeted XSS payload rather than a system compromise. Net: real but minor, patch during routine maintenance.

Exploit ScenarioDerived

An authenticated user holding the WooCommerce Shop Manager role submits crafted input into an Astra theme field that is rendered without adequate sanitization, injecting HTML/script that executes when another user or admin views the affected page. Because the attacker must already hold a privileged store-management account (PR:H), the realistic scenario is a malicious or compromised Shop Manager escalating influence or phishing higher-privileged admins. No public proof-of-concept was identified at the time of analysis.

AnalysisAIv1 – Sep 30, 2026

Content injection in Astra WordPress Theme 4.13.12 and earlier allows an authenticated WooCommerce Shop Manager to insert untrusted markup or script content into affected pages. The flaw is network-reachable and low-complexity but requires high privileges and an active WooCommerce installation, yielding only limited integrity impact with no confidentiality or availability loss; CVSS is 2.7. No public exploit identified at time of analysis, and it is not confirmed actively exploited (CISA KEV).

RemediationAI

Patch availability is not stated in the provided data, so consult the Patchstack advisory at https://patchstack.com/database/wordpress/theme/astra/vulnerability/wordpress-astra-wordpress-theme-theme-4-13-12-content-injection-vulnerability?_s_id=cve for vendor guidance and upgrade Astra WordPress Theme to the latest release after confirming it contains the fix, since the affected range is 4.13.12 and earlier. Because exploitation requires the WooCommerce Shop Manager role, reduce exposure by auditing and removing unused Shop Manager accounts, limiting that role to trusted personnel, and using a role-editing plugin to strip unnecessary capabilities; if store management does not require the role, disable or rename it, and enforce multi-factor authentication for remaining accounts. A WAF or WordPress security plugin with a virtual patch for this issue can provide interim protection, with the trade-off of potential false positives and ongoing rule maintenance.

Technical ContextAI · show details

Astra is a widely deployed WordPress theme from Brainstorm Force, and the issue is classified under CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page), the classic basic XSS/content-injection weakness. The CPE cpe:2.3:a:brainstorm_force:astra_wordpress_theme:*:*:*:*:*:*:*:* identifies the theme as the affected component, with the description limiting impact to versions up to and including 4.13.12. Exploitation requires an account with the WooCommerce Shop Manager role, implying WooCommerce must be installed and active. The CVSS vector AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N confirms network reachability and low attack complexity, but the high privilege requirement and absence of confidentiality or availability impact constrain realistic abuse to malicious insiders or attackers who already control a Shop Manager account. Patchstack reported the issue; the XSS tag aligns with the content-injection classification.
