On #2535192: Security: LoggerChannelInterface doxygen needs a little love → , we patched the interface for logging in drupal 8 to add a security note:

+ * SECURITY NOTE: the caller might also set a 'link' in the $context array
+ * which will be printed as-is by the dblog module under an "operations"
+ * header. Usually this is a "view", "edit" or similar relevant link. Make sure
+ * to use proper, secure link generation facilities; some are listed below.
+ *
+ * @see \Drupal\Core\Logger\RfcLoggerTrait
+ * @see \Psr\Log\LoggerInterface
+ * @see \Drupal\Core\Logger\\LoggerChannelFactoryInterface
+ * @see \Drupal\Core\Utility\LinkGeneratorInterface
+ * @see \Drupal\Core\Routing\LinkGeneratorTrait::l()
+ * @see \Drupal\Core\Entity\EntityInterface::link()

We need to add a similar notice here, but just tell people to use the l() function, with its sanitization features, to make links (the list of "secure link generation facilities" in Drupal 7 is only the l() function).

  • Novice

    It would make a good project for someone who is new to the Drupal contribution process. It's preferred over Newbie.

  • Security improvements

    It makes Drupal less vulnerable to abuse or misuse. Note, this is the preferred tag, though the Security tag has a large body of issues tagged to it. Do NOT publicly disclose security vulnerabilities; contact the security team instead. Anyone (whether security team or not) can apply this tag to security improvements that do not directly present a vulnerability e.g. hardening an API to add filtering to reduce a common mistake in contributed modules.
