Craft CMS Vulnerability CVE-2025-23209: A High-Severity Security Flaw Exposed



A high-severity security flaw has been added to the Known Exploited Vulnerabilities (KEV) catalog by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), highlighting the need for Craft CMS users to address a code injection vulnerability that allows remote code execution. The vulnerability affects versions 4 and 5 of the software, with compromised user security keys being impacted.

  • Craft CMS versions 4 and 5 have been identified with a high-severity vulnerability (CVE-2025-23209) that can lead to remote code execution and unauthorized access to sensitive data.
  • The vulnerability allows attackers to inject malicious code into user systems, bypassing traditional authentication mechanisms.
  • CISA has added the vulnerability to the KEV catalog, urging federal civilian executive branch agencies to apply patches by March 13, 2025.
  • Users are advised to rotate their security keys and ensure their privacy to mitigate the risk posed by this defect.
  • Regular vulnerability scanning, patching, and updating software applications can help prevent exploitation of such defects.



  • The cybersecurity landscape has witnessed numerous high-severity vulnerabilities in recent times, compromising the integrity and confidentiality of sensitive data. The latest such vulnerability to be added to the Known Exploited Vulnerabilities (KEV) catalog by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) pertains to Craft CMS versions 4 and 5. This high-severity security flaw, identified as CVE-2025-23209, has significant implications for users of these software versions.

    Craft CMS is a popular content management system used by numerous organizations worldwide. Its versatility in managing diverse types of content makes it an attractive choice among businesses seeking to streamline their digital platforms. However, the introduction of this vulnerability underscores the need for proactive measures to be taken by Craft CMS users to prevent exploitation of this security defect.

    The vulnerability in question is a code injection vulnerability that allows for remote code execution in vulnerable versions of Craft CMS. This means that an attacker can inject malicious code into a user's system, resulting in unauthorized access and control over sensitive data. The compromised user security keys are particularly susceptible to this vulnerability, as they can be used by attackers to bypass traditional authentication mechanisms.

    The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has taken notice of this vulnerability and has added it to the KEV catalog. This move is indicative of a growing trend where organizations and regulatory bodies are working together to identify and address high-severity vulnerabilities before they become widespread attacks.

    In an advisory released on GitHub, Craft CMS acknowledged that all unpatched versions of Craft with compromised security keys are impacted by this vulnerability. To mitigate the risk posed by this defect, Craft CMS advised users to rotate their security keys and ensure their privacy to alleviate the issue.

    The exact circumstances surrounding the compromise of user security keys remain unclear at present. It is possible that these keys were compromised through phishing attacks or other forms of social engineering. However, it is also conceivable that the vulnerability itself may have been exploited by an attacker to obtain access to a user's system.

    To avoid being caught off guard by this vulnerability, users are advised to apply the necessary fixes as soon as they become available. The release date for these patches has not been officially announced yet; however, Craft CMS maintainers have addressed this issue in versions 4.13.8 and 5.5.8, which contain the necessary security patches.

    In light of this vulnerability, federal civilian executive branch (FCEB) agencies are urged to apply the necessary fixes by March 13, 2025. Failure to do so may expose these organizations to significant risks in terms of data confidentiality and integrity.

    The identification of this high-severity vulnerability underscores the importance of proactive cybersecurity measures. Regular vulnerability scanning, patching, and updating software applications can help prevent exploitation of such defects. Furthermore, the use of robust security protocols, including multi-factor authentication and encryption, can provide an additional layer of protection against unauthorized access to sensitive data.

    In conclusion, the recent addition of CVE-2025-23209 to the KEV catalog by CISA serves as a stark reminder of the ever-present threat posed by high-severity vulnerabilities. Craft CMS users must take immediate action to address this vulnerability and ensure that their systems are patched before it's too late.
