Primes¶
- Inherited-Substrate Risk
- The latent origin condition is the JNDI-lookup feature, a design decision made by Log4j's authors years earlier, dormant and unflagged, that allowed a logged string to trigger a remote class load.
This sourceRecords the Apache Log4j JNDI-lookup remote-code-execution flaw triggered by attacker-controlled strings reaching a log call.

Domain-specific¶
- Injection Weakness
- SQL injection crosses form-field text into a SQL query; OS command injection crosses a filename into a shell command string; stored cross-site scripting crosses a comment field into the HTML/JavaScript rendered in another user's browser; template injection crosses a configuration value into a Jinja or Twig expression evaluator; LDAP, XPath, NoSQL, GraphQL injection do the same in their respective query languages; CRLF injection crosses control characters into HTTP header lines; Log4Shell (CVE-2021-44228) crossed log-message content into a JNDI expression evaluator
This sourceThe vulnerability record stating that an attacker who controls logged messages or parameters can have Log4j2 execute arbitrary code loaded from LDAP servers via its message-lookup feature.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 2 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
