Closes #45645
Closes #45694
Instead of extending
SecureClientUrisExecutor, I introduced a new executor to provide fully configurable client URIs validation.I did not extend
SecureClientUrisExecutorbecause it already enforces HTTPS and disallows wildcards.There is a need to trust specific domains to mitigate SSRF on the JWKS URI (see discussion on #45645) and the same for bad
adminUrlvalues #45694 and changing the behavior ofSecureClientUrisExecutorwhile preserving backward compatibility would have been a bit forced.The new executor
SecureClientUrisPatternExecutorallows configuring:A list of allowed regex patterns.
A list of client URI field to which those patterns should be applied.
Configuration may be more complex, but it is very flexible to cover all the cases of validation of any uri field of the client.
Added dedicated tests and documentation.
