Exploitation Conditions

Exploitation requires victim user interaction (UI:R) - a WordPress user or administrator must be enticed to click a crafted link or view attacker-influenced content served through the Social Rocket plugin (version 1.3.5 or earlier). No authentication is required of the attacker (PR:N), but the payload only executes within the victim's authenticated browser session, so impact is bounded by the privileges and session of whoever is social-engineered. The WordPress site must be running a vulnerable Social Rocket build; sites not using this plugin or already updated past 1.3.5 are unaffected. The description does not specify whether the sink is reflected or stored, which affects how the lure is delivered.

Impact

This is a moderate-severity reflected/stored Cross-Site Scripting flaw (CWE-79) in the Social Rocket WordPress plugin, rated CVSS 7.1 with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L. The network vector, low complexity, and PR:N (unauthenticated) are the aggravating signals, but UI:R materially lowers real-world risk: a victim - typically a logged-in administrator or user - must be induced to interact with attacker-controlled input (visit a crafted link or view a poisoned page) for the payload to fire. The scope change (S:C) reflects script executing in the victim's browser context rather than the server, which is why confidentiality/integrity impacts are only Low and why availability impact (A:L) is debatable for an XSS. No EPSS score, CISA KEV entry, or public POC was provided in the input, so there is no public exploit identified at time of analysis; this sits well below KEV-listed or mass-exploited bugs in priority. Treat as a standard patch-cycle item: real but dependent on social-engineering and not evidence of active, widespread exploitation.

Exploit ScenarioDerived

An attacker crafts a malicious link or input containing a JavaScript payload targeting a vulnerable Social Rocket endpoint and lures a WordPress user or administrator into triggering it. When the victim's browser renders the unsanitized output, the script executes in their session context, enabling session/cookie theft, admin-action forgery, or redirection. No public proof-of-concept was referenced in the provided data.

AnalysisAIv1 – Oct 06, 2026

Cross-site scripting (CWE-79) in the Social Rocket WordPress plugin through version 1.3.5 lets an unauthenticated attacker deliver a script payload that executes in a victim's browser session once that victim is enticed to click a crafted link or view attacker-influenced content rendered through the plugin (CVSS 7.1, AV:N/AC:L/PR:N/UI:R/S:C, scope changed). No credentials are required to construct or deliver the payload, but the script only runs with the privileges of the social-engineered user, so real-world impact is bounded by the role and session of whoever is tricked. This is not a CISA KEV entry and no public exploit code has been identified at time of analysis; the disclosure is medium/moderate risk and the underlying advisory does not clarify whether the injection point is reflected or stored, which determines how the lure must be delivered.

RemediationAI

No vendor-released patch version is identified in the available data, so the immediate action is to check the Social Rocket plugin's WordPress.org page and the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/social-rocket/vulnerability/wordpress-social-rocket-plugin-1-3-5-cross-site-scripting-xss-vulnerability?_s_id=cve) for the newest release and upgrade past 1.3.5 as soon as one is available. If the plugin's social-sharing features are not business-critical, deactivating and removing it eliminates the attack surface outright, at the cost of losing that front-end functionality; if it must stay, deploy a WAF or virtual-patching rule that blocks script-bearing payloads targeting the plugin's endpoints, accepting that generic XSS signatures produce false positives and can be evaded by encoding tricks. Restrict administrative and editor accounts to trusted users, enforce least privilege, and avoid granting unfiltered_html to lower roles to reduce the damage if an admin session is lured, and consider a Content-Security-Policy that disallows inline script - noting that strict CSP frequently breaks unrelated theme and plugin scripts and must be tested in report-only mode first. Continuous monitoring, prompt WordPress plugin inventory review, and phishing-resistant user awareness remain the compensating controls until an official fix is confirmed.

Technical ContextAI · show details

Social Rocket is a WordPress plugin that adds social sharing and social-growth functionality to a site's posts and pages. The flaw is a classic CWE-79 improper-neutralization-of-input-during-web-page-generation problem: attacker-supplied input is echoed back into an HTML response without adequate output encoding or sanitization, so a browser parses embedded markup as script in the context of the WordPress site. The affected package is identified by CPE cpe:2.3:a:socialrocket:social_rocket:*:*:*:*:*:*:*:* (any version up to and including 1.3.5), confirming the CPE vendor/product pairing maps to the social-rocket plugin distributed through the WordPress.org ecosystem. The vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L describes a network-reachable, low-complexity issue requiring no attacker authentication but requiring victim interaction; the scope-changed (S:C) component reflects that code executes in the security context of the vulnerable WordPress site and can therefore affect resources beyond the vulnerable plugin component itself. Because the payload runs in the victim's authenticated browser session, a successfully lured administrator could yield far greater follow-on capability (for example scripted actions performed with admin cookies) than a lured low-privileged subscriber. The single public reference is Patchstack's vulnerability record for the plugin, and no patch or fixed-version detail is provided in the available data.

Executive ViewAI

Why It Matters

Social Rocket, a WordPress social-sharing plugin installed on our public-facing sites at version 1.3.5 and earlier, contains a cross-site scripting flaw that lets an unauthenticated attacker run script in the browser of any employee or customer enticed into clicking a crafted link. Because the plugin has no vendor-released patch and sits on internet-facing sites, every instance running it remains exposed and a successful attack could lead to session theft, credential harvesting, or content tampering under the victim's own access rights. Leadership should treat this as a medium-priority remediation item rather than an emergency: no public exploit code has been identified at time of analysis and exploitation requires the victim to be socially engineered.

Business Impact: Medium
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: deactivate or remove the Social Rocket plugin (version 1.3.5 and earlier) where it is not business-critical; apply WAF/edge filtering for cross-site scripting patterns on plugin endpoints; enforce Content-Security-Policy on WordPress front ends; set HttpOnly and SameSite flags on session cookies; restrict access to pages rendered through the plugin; and monitor vendor channels for a fixed release above 1.3.5.
