Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 11 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 2026-10-25.

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

To mitigate CVE-2025-8847, European organizations should prioritize upgrading to a patched version of RuoYi once available. In the absence of an official patch, immediate steps include implementing strict input validation and output encoding on the noticeTitle and noticeContent parameters to neutralize malicious scripts. Web application firewalls (WAFs) can be configured with custom rules to detect and block typical XSS payloads targeting the /system/notice/edit endpoint. Additionally, organizations should enforce Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Regular security audits and code reviews focusing on input handling in RuoYi applications are recommended to identify and remediate similar vulnerabilities. User awareness training should be conducted to recognize suspicious notices or unexpected behavior in internal applications. Finally, monitoring logs for unusual activity related to the affected endpoint can help detect attempted exploitation attempts early.

Description

A vulnerability was found in yangzongzhuan RuoYi up to 4.8.1. Affected by this vulnerability is the function Edit of the file /system/notice/edit. The manipulation of the argument noticeTitle/noticeContent leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using yangzongzhuan RuoYi versions 4.8.0 or 4.8.1, this XSS vulnerability poses a risk of session hijacking, credential theft, or unauthorized actions performed in the context of authenticated users. This can lead to data leakage, unauthorized access to sensitive information, or manipulation of internal notices and communications. Given that RuoYi is a popular Java-based rapid development platform used in enterprise applications, the vulnerability could affect internal business applications, portals, or intranet systems. The impact is particularly significant for organizations relying on RuoYi for critical internal communications or workflows, as attackers could leverage the XSS flaw to conduct phishing attacks or implant persistent malicious scripts. While the vulnerability does not directly compromise system availability, the potential for data integrity and confidentiality breaches can disrupt business operations and damage organizational reputation. Additionally, compliance with GDPR and other European data protection regulations may be jeopardized if personal data is exposed or mishandled due to exploitation of this vulnerability.
