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: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
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 5 Mar 2024
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

Since no official patches are currently available, organizations should implement immediate mitigations to reduce exposure. These include: 1) Restricting outbound HTTP requests from the WonderCMS server using firewall rules or network segmentation to limit the server's ability to reach unauthorized internal or external endpoints. 2) Implementing input validation and sanitization at the application or web server level to block or filter suspicious pluginThemeUrl parameter values, such as disallowing private IP ranges or localhost addresses. 3) Monitoring and logging all outbound requests initiated by the CMS to detect anomalous or unexpected traffic patterns indicative of SSRF exploitation attempts. 4) Employing web application firewalls (WAFs) with custom rules to detect and block SSRF attack patterns targeting the pluginThemeUrl parameter. 5) Isolating the WonderCMS environment in a restricted network zone with minimal privileges to limit the impact of potential exploitation. 6) Staying updated with WonderCMS vendor advisories for official patches or updates addressing this vulnerability and applying them promptly once released. 7) Conducting regular security assessments and penetration testing focused on SSRF and related vulnerabilities in the CMS environment.

Description

A Server-Side Request Forgery (SSRF) in the getFileFromRepo function of WonderCMS v3.1.3 allows attackers to force the application to make arbitrary requests via injection of crafted URLs into the pluginThemeUrl parameter.

Impact

The primary impact of CVE-2024-27563 is unauthorized server-side HTTP requests initiated by an attacker, which can lead to information disclosure if internal services or metadata endpoints are accessed. This can compromise confidentiality by revealing sensitive internal network details or credentials. Integrity impact is possible if the attacker can influence the server to interact with malicious endpoints, potentially leading to data manipulation or injection attacks. Availability is not directly affected by this vulnerability. The ease of exploitation without authentication and user interaction increases the threat level, especially for publicly accessible WonderCMS installations. Organizations could face data breaches, reconnaissance by attackers for further exploitation, and potential lateral movement within internal networks. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a significant risk if weaponized. Enterprises relying on WonderCMS for web content management should consider this vulnerability a priority to address to avoid potential compromise.
