GitHub Actions documentation untrusted input script injection expressions run shell tag_name release event

💡 Result:

In GitHub Actions, using expressions like ${{ github.event.release.tag_name }} directly within shell commands (e.g., in a run block) creates a significant risk of shell command injection [1][2][3]. This vulnerability occurs because GitHub Actions evaluates and substitutes ${{ }} expressions before the shell script runs [1][4]. If an attacker can control the input—such as by creating a specifically crafted release tag—they can inject malicious shell commands that the runner will execute [1][3]. Even if the input is wrapped in quotes, an attacker may use characters like backticks, semicolons, or additional quotes to break out of the intended context [1][2]. To mitigate this risk, follow these authoritative security practices: 1. Use Intermediate Environment Variables: Never interpolate untrusted input directly into a shell command [2][5][4]. Instead, map the expression to an environment variable in the env section, and then reference that variable using the appropriate shell syntax (e.g., "$VARIABLE" in Bash) [5][6][3]. Because the environment variable is passed as data rather than being pre-processed by the expression evaluator, it cannot alter the structure of the shell command [2][3]. Example of safe usage: env: RELEASE_TAG: ${{ github.event.release.tag_name }} run: | echo "Processing release: $RELEASE_TAG" 2. Treat Contexts as Untrusted: Contexts such as github.event.release.tag_name, issue titles, PR bodies, and head references should always be treated as untrusted input [1][7][3]. 3. Use Code Scanning: Enable GitHub code scanning with CodeQL, which includes built-in rules to detect unsafe interpolation of untrusted input in workflows [2][4]. 4. Security Hardening regarding Git Tags: Be aware that Git tags are mutable references [8][9]. Referencing actions or inputs by mutable tags (e.g., @v2) can lead to tag-hijacking or drift, where a tag is force-pushed to point to a malicious commit [8][9]. For maximum security, pin actions to their immutable commit SHA (e.g., @a1b2c3d...) rather than a tag [8][9].

Pass release tag values through env before shell use. Both workflows interpolate github.event.release.tag_name into shell source. A valid Git tag can contain $(); the shell evaluates it in RAW_TAG="${{ ... }}". Pass the event value through step env and use "$RAW_TAG". Pass derived outputs through env before later shell commands.

I belive we don't need the -tmp suffix, we can create the tag like v5.6.0 and than override that tag. That would be more straightforward during the release so we don't have to remember special naming convention.

  git tag -f -a "${RAW_TAG}" -m "Release ${RAW_TAG}"

If we don't have the -temp suffix, we don't have to check this, we simply override the tag as mentioned before, then we don;t have to edit the release, since release just point to a ref name on GitHub

Finalize the tag after Maven Central publishing succeeds.

This step creates the final tag, retargets the GitHub Release, and deletes the temporary tag before ./mvnw package deploy -Prelease. If publishing fails, the public release still points to the final tag. A retry then fails when git tag -a "${FINAL_TAG}" finds the existing tag.

Move final-tag and release finalization after a successful deploy. Alternatively, make this sequence idempotent and verify that an existing final tag targets the intended release commit.

Do not hide temporary-tag deletion errors.

If the remote rejects deletion, such as for a protected tag, || true marks the workflow successful and leaves the temporary snapshot tag published. Ignore only an explicitly absent remote ref. Fail for other deletion errors.
