CVE-2024-56145
CVE-2024-56145 is a security flaw in Craft CMS, software for building and running websites. Attackers can run their own code on Craft CMS. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 2 Jun 2025.[1]
Craft CMS is business software or equipment. Most families won’t have it, but attackers break into it to get inside companies, and from there to what those companies hold about their customers, patients and staff. Craft CMS has published a fix or advice.
Description
CISA calls it a code injection in Craft CMS Craft CMS. In its words: “Craft CMS contains a code injection vulnerability. Users with affected versions are vulnerable to remote code execution if their php.ini configuration has `register_argc_argv` enabled.”[1]
The CVE record adds: “Craft is a flexible, user-friendly CMS for creating custom digital experiences on the web and beyond. Users of affected versions are affected by this vulnerability if their php.ini configuration has `register_argc_argv` enabled. For these users an unspecified remote code execution vector is present. Users are advised to update to version 3.9.14, 4.13.2, or 5.5.2. Users unable to upgrade should disable `register_argc_argv` to mitigate the issue.”[2]
The underlying weakness is code injection (CWE-94), in MITRE’s list of common software weaknesses.
It scores 9.8 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it; Craft CMS’s advisory has them[3]. CISA names the product as Craft CMS Craft CMS.
Most families won’t have Craft CMS; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 2 Jun 2025, 166 days after it was made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 23 Jun 2025 to fix it.[1]
FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 97%. That’s in the top 1% of the flaws it scores.[4]
CISA assesses it as automatable: attackers can run it against many targets at once.
CISA doesn’t say who was attacked, or how.
Fix
Craft CMS has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.”[1]
- Check whether you use it.Craft CMS is business software or equipment, so most families won’t have it. If you run a business, or work from home on company equipment, ask whoever looks after your IT.
- Send this page to your IT person.Ask them to confirm it’s fixed, or not in use. CISA gave US government agencies until 23 Jun 2025 to fix it.
- If it can’t be fixed, take it offline.CISA’s advice when there’s no fix is to stop using the product, or take it off the internet, until there is one.
You can’t fix someone else’s server, but you can watch for what follows a break-in like this: a breach notice, a password reset you didn’t ask for, or a scam message that knows things it shouldn’t. HARD watches for those for you and your family.
