CVE-2025-26754 is classified as a medium-severity vulnerability due to its CVSS score of 6.5. This vulnerability allows improper neutralization of input during web page generation, specifically in the bPlugins Timeline Block plugin, which facilitates stored Cross-site Scripting (XSS). Attackers may leverage this vulnerability to inject malicious scripts that execute in the context of the user's browser. The potential consequences include data theft, session hijacking, and unauthorized actions performed on behalf of the user.
Organizations using affected versions of the bPlugins Timeline Block should prioritize remediation. The vulnerability is present in all versions prior to and including version 1.1.1. As this issue falls under the category of stored XSS, it poses a significant risk, particularly in environments where user-generated content is displayed without adequate sanitization.
Given that the vulnerability was published on February 17, 2025, organizations should act promptly to mitigate risks associated with exploitation. The urgency for defenders is moderate, and organizations are advised to incorporate this patch into their normal update cycle.
As of now, there are no known public exploits or proofs of concept for this vulnerability, but the lack of current exploitation does not diminish the potential risks involved. Organizations should remain vigilant and proactive in their security measures.
Risk to organizations includes the potential for attackers to execute arbitrary scripts in the context of users' browsers, which could lead to significant data breaches or unauthorized actions. Organizations should prioritize patching immediately.
Vulnerability Details
The official CVE description indicates that this vulnerability allows improper neutralization of input during web page generation, specifically enabling stored XSS in the bPlugins Timeline Block. The affected product is the Timeline Block plugin, with versions from n/a up through 1.1.1 being vulnerable.
CWE-79 categorizes this vulnerability under improper neutralization of input. The CVSS score of 6.5 reflects a medium severity level, indicating that while the exploitation complexity is low, the requirement for user interaction amplifies the risk.
Technical Analysis
The root cause of this vulnerability lies in the inadequate sanitization of user input within the bPlugins Timeline Block plugin. Attackers can exploit this by submitting malicious scripts that are stored and subsequently rendered in users' browsers without the necessary filtering.
The attack vector for this vulnerability is network-based, requiring low attack complexity and low privileges. User interaction is required, as the malicious payload must be triggered by a user accessing a compromised page.
The potential impacts from this vulnerability include low confidentiality, integrity, and availability, as the exploitation primarily affects user sessions and interactions rather than the underlying system.
Risk & Impact Analysis
In real-world deployments, this vulnerability poses a risk primarily to users who interact with the vulnerable plugin. Attackers may exploit this weakness to execute scripts that can capture sensitive information from users, such as cookies or session tokens.
The potential blast radius includes all users who access the affected Timeline Block, especially in scenarios where social engineering tactics are employed to lure users into triggering the malicious scripts.
Given that the CVSS score is 6.5 and the vulnerability is not included in the Known Exploited Vulnerabilities (KEV) catalog, organizations should still maintain a proactive stance on security, as the absence of current exploits should not lead to complacency.

|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
This vulnerability affects all versions of the bPlugins Timeline Block plugin prior to and including version 1.1.1. Organizations should verify their plugin versions and apply necessary updates.
Mitigation & Remediation
To remediate this vulnerability, organizations should upgrade to the latest version of the bPlugins Timeline Block plugin. If immediate patching is not possible, consider implementing content security policies (CSP) to mitigate the impact of potential XSS attacks.
For additional security, organizations should conduct regular security reviews and testing, such as penetration testing, to identify and address vulnerabilities in their web applications.
Detection Guidance
Organizations should monitor for abnormal logging patterns and user behavior that may indicate exploitation attempts. Additionally, monitoring network traffic for known attack patterns related to XSS can aid in early detection.
AppSecure Threat Intelligence Insight
