Summary of what we know so far:
- The vulnerability CVE-2021-44228 affects log4j 2.x only. It was introduced in version 2.0-beta9 and fixed in 2.15.0-rc2. log4j 1.x is unaffected. For the vulnerability to be present, log4j-core-2.*.jar (or a shaded equivalent) needs to be bundled with the plugin, anything else (slf4j bridges, API jars, log4j 1.x) doesn't include the vulnerable class (see below).
- Recent JREs prohibit the specific LDAP RCE exploit, but other exploits exist (e.g. capturing env vars).
- Maven Shade Plugin may rename packages, so there may be matches in other packages (but a patched usage-in-plugins found none in latest plugin releases)
- Further plugins may have included the library in older releases. We are working on a list.
- log4j 2.16.0 includes a fix for another security vulnerability, see https://lists.apache.org/thread/83y7dx5xvn3h5290q1twn16tltolv88f It's low severity, and requires a nondefault configuration to be exploitable (or attackers able to configure logging). It affects 2.0-beta9 through 2.15.0 (inclusive) and is fixed in 2.16.0.
- The specific affected classes are org.apache.logging.log4j.core.lookup.JndiLookup and org.apache.logging.log4j.core.net.JndiManager (previously org.apache.logging.log4j.core.appender.JndiManager). The former should be removed manually according to https://logging.apache.org/log4j/2.x/security.html when using affected versions. This applied to both vulnerabilities.

Just found that the plugin, analysis-model-api, uses the log4j library
daveaugustus the use of log4j does not make the plugin vulnerable. Unless you have specific details that show that a vulnerable version of log4j is included in the plugin, then its use of log4j is not an issue. The most recent release of analysis model api plugin includes log4j 2.19.0 in its packaging. The log4j 2.19.0 release is not vulnerable.
I'm stuck with releasing it, as I can't access the account I was using to publish new versions
I've submitted a permission change in: https://github.com/jenkins-infra/repository-permissions-updater/pull/2269
once this one lands in, and I can push something, 2.2.x will be released and will include the fixes for the log4j, along with some more stuff
