CVE-2026-24565 identifies a vulnerability in the bPlugins B Accordion plugin, specifically versions up to and including 2.0.0. The issue involves the insertion of sensitive information into data sent by the plugin, which can be retrieved by an attacker. This vulnerability allows an attacker with low privileges (PR:L) to remotely access sensitive embedded data without requiring user interaction (UI:N). The attack vector is network-based (AV:N), meaning exploitation can occur remotely. The vulnerability impacts confidentiality (C:H) but does not affect integrity (I:N) or availability (A:N). The plugin likely fails to properly sanitize or restrict sensitive data included in its output, exposing it to unauthorized retrieval. No patches or known exploits are currently available, indicating that the vulnerability is newly disclosed and not yet actively exploited. The lack of CWE classification suggests the vulnerability may be specific to the plugin's data handling logic rather than a common coding flaw. Given the plugin's use in web environments, attackers could leverage this flaw to harvest sensitive information embedded in accordion content or configuration, potentially leading to data leakage and privacy violations. The CVSS 3.1 vector and score of 6.5 reflect a medium severity level, balancing the high confidentiality impact against the requirement for low privileges and no user interaction.

For European organizations, this vulnerability poses a risk of sensitive data exposure through web applications using the vulnerable B Accordion plugin. Confidential information embedded in accordion content or plugin data could be retrieved by attackers with low privileges, potentially leading to data breaches or compliance violations under GDPR. Although the vulnerability does not affect system integrity or availability, the confidentiality impact can undermine trust, cause reputational damage, and trigger regulatory penalties. Organizations in sectors handling sensitive personal or business data—such as finance, healthcare, and government—are particularly at risk. The remote exploitability increases the attack surface, especially for publicly accessible websites. The absence of known exploits currently reduces immediate risk but also means organizations must proactively address the vulnerability before attackers develop weaponized exploits. The medium severity indicates that while the threat is significant, it is not critical, allowing time for measured response and patching.

1. Immediately audit and inventory all instances of the bPlugins B Accordion plugin in use, identifying versions at or below 2.0.0. 2. Restrict access to the plugin’s administrative and configuration interfaces to trusted users only, minimizing the risk of low-privilege exploitation. 3. Monitor network traffic and web application logs for unusual requests or data retrieval patterns that may indicate exploitation attempts targeting the plugin. 4. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests related to the plugin’s data endpoints. 5. Until an official patch is released, consider disabling or removing the vulnerable plugin from production environments, especially on sites handling sensitive data. 6. Engage with the vendor or community to obtain updates or patches as soon as they become available and apply them promptly. 7. Review and sanitize any sensitive data embedded within accordion content to minimize exposure if exploitation occurs. 8. Educate development and security teams about the vulnerability to ensure rapid response and awareness.
