Official Description

The Login/Signup Popup plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on several functions in versions up to, and including, 1.4. This makes it possible for authenticated attackers to inject arbitrary web scripts into the plugin settings that execute if they can successfully trick a user into performing an action such as clicking on a link.

Risk Analysis

The Login/Signup Popup plugin for WordPress, versions up to 1.4, is vulnerable to an authorization bypass. This is due to missing capability checks on several functions. Authenticated attackers can inject arbitrary web scripts into plugin settings, leading to cross-site scripting (XSS) if a user clicks a malicious link. The confirmed exploitation in the wild makes this a critical vulnerability.

This vulnerability is actively exploited in the wild and is listed in CISA's KEV catalog. Authenticated attackers can remotely exploit this flaw to inject malicious scripts.

Recommended Action

Upgrade the Login/Signup Popup plugin to a version beyond 1.4. Implement robust input validation and output encoding to prevent script injection vulnerabilities.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2020-36715 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2020-36715 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
