CVE-2025-24893
CVE-2025-24893 is a security flaw in XWiki Platform. Attackers can run their own code on XWiki Platform. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 30 Oct 2025.[1]
XWiki Platform 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. XWiki has published a fix or advice.
Description
CISA calls it an eval injection in XWiki Platform. In its words: “XWiki Platform contains an eval injection vulnerability that could allow any guest to perform arbitrary remote code execution through a request to SolrSearch.”[1]
The CVE record adds: “XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any guest can perform arbitrary remote code execution through a request to `SolrSearch`. This impacts the confidentiality, integrity and availability of the whole XWiki installation. To reproduce on an instance, without being logged in, go to `<host>/xwiki/bin/get/Main/SolrSearch?media=rss&text=%7D%7D%7D%7B%7Basync%20async%3Dfalse%7D%7D%7B%7Bgroovy%7D%7Dprintln%28"Hello%20from"%20%2B%20"%20search%20text%3A"%20%2B%20%2823%20%2B%2019%29%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D%20`. If there is an output, and the title of the RSS feed contains `Hello from search text:42`, then the instance is vulnerable. This vulnerability has been patched in XWiki 15.10.11, 16.4.1 and 16.5.0RC1. Users are advised to upgrade. Users unable to upgrade may edit…”[2]
The underlying weakness is CWE-95, 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; XWiki’s advisory has them[3]. CISA names the product as XWiki Platform.
Most families won’t have XWiki Platform; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 30 Oct 2025, 252 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 20 Nov 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 over 99%. 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
XWiki 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.XWiki Platform 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 20 Nov 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.
