CVE-2022-41853
Those using java.sql.Statement or java.sql.PreparedStatement in hsqldb (HyperSQL DataBase) to process untrusted input ma
Those using java.sql.Statement or java.sql.PreparedStatement in hsqldb (HyperSQL DataBase) to process untrusted input may be vulnerable to a remote code execution attack. By default it is allowed to call any static method of any Java class in the classpath resulting in code execution. The issue can be prevented by updating to 2.7.1 or by setting the system property "hsqldb.method_class_names" to classes which are allowed to be called.
For example, System.setProperty("hsqldb.method_class_names", "abc") or Java argument -Dhsqldb.method_class_names="abc" can be used. From version 2.7.1 all classes by default are not accessible except those in java.lang.Math and need to be manually enabled.

How to read a CVE - triage first, then detect and patch
This page is every public fact about CVE-2022-41853, 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).
