Lifecycle Timeline
2DescriptionCVE.org
The Instant-Quote.co Quotation Page plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Shortcode Attributes in all versions up to, and including, 1.3.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. A Contributor-level user can trigger execution against higher-privileged users by embedding the malicious shortcode in a post submitted for review, causing the injected scripts to execute when an administrator previews or views the post.
AnalysisAI
Stored Cross-Site Scripting in the Instant-Quote.co Quotation Page WordPress plugin (all versions ≤1.3.4) allows authenticated attackers with contributor-level access to inject persistent malicious scripts via unsanitized shortcode attributes. The changed-scope CVSS vector (S:C) reflects that injected scripts execute in victim browsers rather than the server, and the plugin's shortcode is exploitable through the WordPress post review workflow - a contributor can embed a malicious shortcode in a draft submitted for editor or administrator review, causing the payload to execute when a privileged user previews the post. No public exploit has been identified and EPSS is very low at 0.04% (12th percentile), indicating limited opportunistic exploitation risk, though the cross-privilege escalation path warrants attention on multi-author WordPress sites.
Technical ContextAI
CWE-79 (Improper Neutralization of Input During Web Page Generation) describes the root cause: WordPress shortcodes accept key-value attributes that are processed server-side and rendered into HTML; the plugin fails to apply adequate sanitization on input and escaping on output at two discrete code locations - IQ-quotation-page.php line 339 and line 429 (per WordPress plugin trac references). WordPress shortcode attributes are a common injection vector because plugin developers frequently pass raw attribute values directly into HTML output without wp_kses, esc_attr, or esc_html wrapping. The CVSS vector AV:N/AC:L/PR:L/UI:N/S:C reflects that exploitation is network-reachable, requires no unusual conditions, demands only low-privilege credentials, and that the impact scope crosses the vulnerable component boundary into visiting users' browser contexts. The affected CPE corresponds to the 'iq-quotation-page' plugin slug on the WordPress.org repository, versions 0 through 1.3.4 inclusive.
RemediationAI
No vendor-released patched version has been identified in the available data at time of analysis - site administrators should monitor the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/f7140053-a3c3-44c4-bc83-2e9b9e8853d6 and the WordPress.org plugin repository for a patched release. Until a fix is published, the primary compensating control is to deactivate or uninstall the Instant-Quote.co Quotation Page plugin entirely, which eliminates the attack surface with no functional trade-off if quotation functionality is non-critical. If the plugin must remain active, administrators should audit and revoke contributor-level roles from untrusted users, as contributor access is the minimum privilege threshold for exploitation. Additionally, configuring WordPress so that contributor posts require explicit administrator approval before preview - and training administrators not to preview untrusted drafts - disrupts the cross-privilege escalation path described in the CVE. Web Application Firewall rules targeting shortcode attribute injection patterns (available via Wordfence Premium) may provide detection and blocking capability as a defense-in-depth measure.
