Risk actors have been noticed exploiting two newly disclosed important safety flaws in Craft CMS in zero-day assaults to breach servers and achieve unauthorized entry.
The assaults, first noticed by Orange Cyberdefense SensePost on February 14, 2025, contain chaining the beneath vulnerabilities –
- CVE-2024-58136 (CVSS rating: 9.0) – An improper safety of alternate path flaw within the Yii PHP framework utilized by Craft CMS that might be exploited to entry restricted performance or assets (A regression of CVE-2024-4990)
- CVE-2025-32432 (CVSS rating: 10.0) – A distant code execution (RCE) vulnerability in Craft CMS (Patched in variations 3.9.15, 4.14.15, and 5.6.17)
In response to the cybersecurity firm, CVE-2025-32432 resides in a built-in picture transformation function that enables web site directors to maintain photos to a sure format.
“CVE-2025-32432 depends on the truth that an unauthenticated consumer may ship a POST request to the endpoint liable for the picture transformation and the information inside the POST could be interpreted by the server,” safety researcher Nicolas Bourras stated.
“In variations 3.x of Craft CMS, the asset ID is checked earlier than the creation of the transformation object whereas in variations 4.x and 5.x, the asset ID is checked after. Thus, for the exploit to perform with each model of Craft CMS, the menace actor must discover a legitimate asset ID.”
The asset ID, within the context of Craft CMS, refers back to the approach doc recordsdata and media are managed, with every asset given a singular ID.
The menace actors behind the marketing campaign have been discovered to run a number of POST requests till a legitimate asset ID is found, after which a Python script is executed to find out if the server is weak, and if that’s the case, obtain a PHP file on the server from a GitHub repository.
“Between the tenth and the eleventh of February, the menace actor improved their scripts by testing the obtain of filemanager.php to the net server a number of occasions with a Python script,” the researcher stated. “The file filemanager.php was renamed to autoload_classmap.php on the twelfth of February and was first used on the 14th of February.”

Susceptible Craft CMS Cases by Nation |
As of April 18, 2025, an estimated 13,000 weak Craft CMS cases have been recognized, out of which almost 300 have been allegedly compromised.
“In case you examine your firewall logs or net server logs and discover suspicious POST requests to the actions/property/generate-transform Craft controller endpoint, particularly with the string __class within the physique, then your web site has no less than been scanned for this vulnerability,” Craft CMS stated in an advisory. “This isn’t a affirmation that your web site has been compromised; it has solely been probed.”
If there’s proof of compromise, customers are suggested to refresh safety keys, rotate database credentials, reset consumer passwords out of an abundance of warning, and block malicious requests on the firewall degree.
The disclosure comes as an Energetic! Mail zero-day stack-based buffer overflow vulnerability (CVE-2025-42599, CVSS rating: 9.8) has come underneath energetic exploitation in cyber assaults focusing on organizations in Japan to realize distant code execution. It has been fastened in model 6.60.06008562.
“If a distant third-party sends a crafted request, it could be doable to execute arbitrary code or trigger a denial-of-service (DoS),” Qualitia stated in a bulletin.
