Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.hsqldb:hsqldb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.hsqldb:hsqldb to 2.7.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-41853 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Workaround published by Red Hat
By default, the static methods of any class that is on the classpath are available for use and can compromise security in some systems. The optional Java system property, hsqldb.method_class_names, allows preventing access to classes other than java.lang.Math or specifying a semicolon-separated list of allowed classes. A property value that ends with .* is treated as a wild card and allows access to all class or method names formed by substitution of the * (asterisk). In the example below, the property has been included as an argument to the Java command. java -Dhsqldb.method_class_names="org.me.MyClass;org.you.YourClass;org.you.lib.*" [the rest of the command line] The above example allows…
