dep: Go bump github.com/open-policy-agent/opa from 0.24.0 to 0.25.2

[dependabot]

Bumps github.com/open-policy-agent/opa from 0.24.0 to 0.25.2.

Release notes

Sourced from github.com/open-policy-agent/opa's releases.

v0.25.2

This release extends the HTTP server authorizer (--authorization=basic) to supply the HTTP message body in the input document. See the Authentication and Authorization section in the security documentation for details.

v0.25.1

This release contains a fix for running OPA under Docker with a non-default working directory (#2974):

/opa: error while loading shared libraries: libwasmer.so: cannot open shared object file: No such file or directory

v0.25.0

This release contains a number of improvements and fixes. Importantly, this release includes a notable change to built-in function error handling. See the section below for details.

Built-in Function Error Handling

Previously, built-in function errors would cause policy evaluation to halt immediately. Going forward, by default, built-in function errors no longer halt evaluation. Instead, expressions are treated as false/undefined if any of the invoked built-in functions return errors.

This change resolves a common issue people face when passing unsanitized input values to built-in functions. For example, prior to this change the expression io.jwt.decode("GARBAGE") would halt evaluation of the entire policy because the string is not a valid encoding of a JSON Web Token (JWT). If the expression was io.jwt.decode(input.token) and the user passed an invalid string value for input.token the same error would occur. With this change, the same expression is simply undefined, i.e., there is no result. This means policies can use negation to test for invalid values. For example:

decision := {"allowed": allow, "denial_reason": reason}
default allow = false
allow {
io.jwt.verify_hs256(input.token, "secret")
[_, payload, _] := io.jwt.decode(input.token)
payload.role == "admin"
}
reason["invalid JWT supplied as input"] {
not io.jwt.decode(input.token)
}

If you require the old behaviour, enable "strict" built-in errors on the query:

Caller	Example
HTTP	POST /v1/data/example/allow?strict-builtin-errors
Go (Library)	rego.New(rego.Query("data.example.allow"), rego.StrictBuiltinErrors(true))
CLI	opa eval --strict-builtin-errors 'data.example.allow'

If you have implemented custom built-in functions and require policy evaluation to halt on error in those built-in functions, modify your built-in functions to return the topdown.Halt error type.

Built-in Functions

This release includes a few new built-in functions:

• base64url.encode_no_pad, hex.encode, and hex.decode for dealing with encoded data (#2849) authored by @johanneslarsson
