Source code reveals how software works, helping security teams identify vulnerabilities, exposed secrets, and unsafe logic before attackers can exploit them.

Background for this topic.
Source code is the human-readable text programmers write in a language such as Python, Java, or C before it is compiled or interpreted into a running program. It defines the program’s logic, data handling, and interactions with operating systems, networks, and other services. Source code may include application code, scripts, and configuration that controls software behavior.
In security, exposed or improperly protected repositories can disclose credentials, private keys, internal endpoints, or details that help attackers find exploitable flaws. Vulnerabilities may also enter through unsafe coding patterns, outdated dependencies, or malicious changes to code and build pipelines. Defenses include least-privilege repository access, secret scanning, peer review, static analysis, dependency and software-composition checks, and integrity controls for releases. Preserving commit history and build provenance helps investigators determine what changed and whether delivered software matches reviewed source.
And the earlier React2Shell patch is vulnerable If you're running React Server Components, you just can't catch a break. In addition to already-reported flaws, newly discovered bugs allow attackers to hang vulnerable servers and potentially leak Server Function source code, so anyone using RSC or frameworks that support it should patch quickly.…
The React team has released fixes for two new types of flaws in React Server Components (RSC) that, if successfully exploited, could result in denial-of-service (DoS) or source code exposure
