Scope: Changed
Confidentiality: Low
Integrity: Low
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Immediate upgrade of the Ebook Store WordPress plugin to version 5.8015 or later once available to ensure the vulnerability is patched. 2. Implement Web Application Firewall (WAF) rules that detect and block suspicious request patterns targeting the REQUEST_URI parameter to mitigate exploitation attempts before patching. 3. Enforce Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the impact of XSS attacks. 4. Educate users and staff about phishing risks and the dangers of clicking on untrusted links, especially those that appear to come from the organization's domain. 5. Regularly audit and monitor web server logs for unusual request patterns or repeated attempts to exploit this vulnerability. 6. Encourage users to update their browsers to the latest versions to benefit from modern XSS protections. 7. Conduct security testing and code reviews on custom WordPress plugins and themes to ensure proper input validation and output encoding practices are followed. 8. If immediate patching is not possible, consider temporarily disabling the Ebook Store plugin or restricting access to it via IP whitelisting or authentication controls.

Description

The Ebook Store WordPress plugin before 5.8015 does not escape the $_SERVER['REQUEST_URI'] parameter before outputting it back in an attribute, which could lead to Reflected Cross-Site Scripting in old web browsers.

Impact

For European organizations using WordPress sites with the Ebook Store plugin, this vulnerability poses a risk primarily to the confidentiality and integrity of user data. Attackers exploiting this vulnerability could hijack user sessions, steal sensitive information, or perform actions on behalf of users, potentially leading to account compromise or unauthorized transactions. While the impact on availability is negligible, the reputational damage and potential regulatory consequences under GDPR for data breaches involving personal data could be significant. The requirement for user interaction (clicking a malicious link) somewhat limits the exploitability, but phishing campaigns could be used to lure users into triggering the attack. Organizations with customer-facing WordPress sites that utilize this plugin should be particularly cautious, as attackers could target customers or employees. The vulnerability's effect on older browsers means that users who have not updated their browsers are at higher risk, which can be common in certain corporate environments with legacy systems. Overall, the threat could lead to moderate operational disruption and data exposure risks for European entities, especially in sectors like e-commerce, publishing, and education where Ebook Store plugin usage is more prevalent.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
