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: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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 31 Dec 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

Since no official patches are currently available, European organizations should implement several specific mitigations: 1) Conduct immediate code audits focusing on the Save function and the handling of the 'content' parameter to identify and sanitize inputs rigorously, employing strict whitelisting and escaping techniques. 2) Deploy web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the vulnerable endpoint. 3) Restrict network access to the Layout API Endpoint to trusted IP addresses or internal networks where feasible. 4) Monitor logs for unusual activity or attempts to exploit the 'content' parameter remotely. 5) Consider isolating or segmenting servers running KodiCMS to limit potential lateral movement if compromised. 6) Prepare for rapid patch deployment once the vendor releases an official fix by establishing a vulnerability management process. 7) Educate development and operations teams about secure coding practices to prevent similar injection flaws in the future.

Description

A security vulnerability has been detected in Kohana KodiCMS up to 13.82.135. This impacts the function Save of the file cms/modules/kodicms/classes/kodicms/model/file.php of the component Layout API Endpoint. The manipulation of the argument content leads to code injection. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, the impact of CVE-2025-15393 can be substantial, especially for those using Kohana KodiCMS to manage critical web content or internal portals. Successful exploitation could allow attackers to execute arbitrary code remotely, potentially leading to unauthorized access to sensitive data, modification or deletion of content, and disruption of services. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), and financial losses. Given the lack of vendor response and patches, organizations face prolonged exposure. The medium CVSS score reflects moderate risk, but the ease of remote exploitation without authentication increases urgency. Organizations in sectors such as government, finance, healthcare, and media, which often rely on CMS platforms, are particularly at risk. Additionally, the vulnerability could be leveraged as a foothold for further lateral movement within networks, amplifying the potential damage.
