CVE-2026-41000
Wss4jSecurityInterceptor did not consistently wire Apache WSS4J ReplayCache instances into RequestData for validation-ti
Wss4jSecurityInterceptor did not consistently wire Apache WSS4J ReplayCache instances into RequestData for validation-time checks. As a result, protections against replay of UsernameToken nonces and creation timestamps, Timestamp elements, and certain SAML one-time-use semantics could be ineffective even when operators configured a replay cache on the interceptor. Affected versions: Spring Web Services 5.0.0 through 5.0.1.
4.1.0 through 4.1.3.
4.0.0 through 4.0.18.
3.1.0 through 3.1.8.

How to read a CVE - triage first, then detect and patch
This page is every public fact about CVE-2026-41000, cross-linked. Its job is to answer one question fast - does this need my attention now? - and then hand you the two things you do about it. Here is how an analyst reads it.
Triage: should I act now? Four signals, and they are not interchangeable:
CVSSseverity - how bad it is IF exploited, 0-10. A high CVSS alone is not urgency; a flaw can be a perfect 10 and never actually be attacked.
EPSSprobability - a model’s estimate of the chance it is exploited in the next 30 days, 0-1. This is the “will it actually happen” signal.
CISA KEVconfirmed - it is being exploited in the wild right now. The strongest signal on the page; KEV beats any score.
Weaponisedavailability - public exploits / PoCs, and especially Metasploit modules rated Excellent / Great. Reliable, packaged exploit code means low-skill attackers can use it today.
How they combine: KEV, or a dependable Metasploit module, means patch now regardless of CVSS. High CVSS + low EPSS + no exploit is real but not an emergency - schedule it. Low CVSS but KEV-listed still gets patched now. The verdict above already weighed these for you; this is how it got there.
Then what - two workflows:
Detectwhen you cannot patch today, follow this CVE to the ATT&CK techniques it enables, then Build a SIEM detection (the green button) - author a rule, test it in Atomic, deploy it. That buys visibility while the patch waits.
PatchAffected products / packages tell you if you are exposed; Fixed versions by distribution and Vendor advisories give the exact version that closes it.
Reading order for the panels below: verdict + badges, then Public exploits / Metasploit (is it weaponised), then ATT&CK techniques + Sigma / IDS rules (can I detect it), then Affected products / packages + Fixed versions (am I exposed, what patches it), then Threat actors / IOCs (who uses it), then Scoring & timeline / references (the evidence).

SSVC asks the questions that actually drive patch urgency: is it being exploited, can attacks be automated, and how total is the impact.
