fix(security): patch known vulnerabilities in the build toolchain

[mattinannt]

Why nothing was ever reported

GitHub's dependency graph for this repo (GET /repos/formbricks/android/dependency-graph/sbom) contains six packages — all of them GitHub Actions. Not one Gradle dependency is in it.

That's not a misconfiguration, it's how GitHub works: it doesn't resolve build.gradle.kts / libs.versions.toml on its own, and a Gradle project only reaches the dependency graph through dependency submission. So Dependabot alerts have never been able to see a single Gradle dependency of this SDK. The six Actions it can see are all advisory-free today, which is why the alert list looks clean.

What was actually vulnerable

Two separate dependency surfaces, scanned against OSV:

Surface	What it is	Before	After
Project configurations	releaseRuntimeClasspath, AGP's _internal-unified-test-platform-*	40 advisories	0 (269 artifact versions)
Gradle plugin classpath	the JARs implementing AGP, Sonar etc., resolved before any project build script runs	9 advisories	0 (27 artifact versions)

All build-time only. releaseRuntimeClasspath and releaseCompileClasspath are unchanged, so the published AAR and its POM are unaffected.

The two changes

1. Raise AGP's vulnerable transitives

Artifact	Was	Now	Cleared
io.netty:netty-* (9 modules)	4.1.93.Final	4.1.138.Final	30, incl. CVE-2026-75595 (critical), CVE-2025-24970, CVE-2024-29025
com.google.protobuf:protobuf-{java,kotlin,java-util}	3.22.3 / 3.24.4	3.25.9	CVE-2024-7254 (high)

Both come from AGP's Unified Test Platform. Nothing in this project declares them, and they have to reach AGP's internal _internal-unified-test-platform-* configurations, which don't extend implementation — so they go through resolutionStrategy rather than ordinary dependency constraints.

They are floors, not overrides. A bare useVersion also drags a newer version back down, so an agp bump shipping netty above 4.1.138 would have been silently reverted to today's value — and this PR makes those bumps weekly. A numeric comparison leaves anything at or above the floor alone.

2. Remove the Dokka plugin

Everything else — Jackson, jsoup, woodstox, 15 advisories across both surfaces — came from Dokka, and nothing in this repo runs Dokka. publishAndReleaseToMavenCentral --dry-run resolves to AGP's own javaDocReleaseGeneration + javaDocReleaseJar with no dokka* task anywhere; no workflow or doc invokes it either. The plugin declaration was its only reference in the repo.

Upgrading was measured first and rejected: Dokka 2.2.0 still resolves Jackson 2.15.3, and 2.15.x introduces GHSA-3pjw-73gf-8qr5 and GHSA-72hv-8253-57qq that 2.14.3 doesn't have — 15 advisories become 14. Removing the plugin takes Jackson, jsoup and woodstox out of the build entirely, which is how both surfaces reach zero.

Trade-off: this removes ./gradlew dokkaHtml as a local capability. Nothing in CI, publishing or the README used it, but if anyone generates those docs by hand, restoring the plugin is a one-line revert — and roughly 14 advisories come back with it.

Also

• .github/dependabot.yml — weekly Gradle and GitHub Actions version updates, androidx and kotlin grouped.
• .github/workflows/dependency-submission.yml — submits the resolved Gradle graph on pushes to main, so Dependabot alerts can finally see Gradle dependencies. This is the part that stops the next batch going unnoticed.
• Documented in the catalog that Dependabot cannot bump the two floor entries — its Gradle parser only reaches [versions] through a version.ref, and nothing references them. As floors, a stale entry is inert rather than harmful.

Verification

• ./gradlew :android:assembleRelease — green, AAR produced.
• :android:dependencies and :android:buildEnvironment — both rescanned against OSV, 0 advisories each.
• publishAndReleaseToMavenCentral --dry-run — unchanged before and after, same two AGP tasks producing the javadoc jar.
• releaseRuntimeClasspath / releaseCompileClasspath diffed against main — identical.

Thanks to @pandeymangg, whose review caught that the Dokka justification didn't hold and that the pins were overriding downward — both are fixed in dc03ae9.

Walkthrough

The change adds weekly Dependabot updates for Gradle and GitHub Actions. It adds a workflow that submits the Gradle dependency graph on pushes to main or manual dispatch. It adds version catalog entries and Gradle resolution rules that pin selected Netty, Protobuf, Jackson, and Jsoup toolchain dependencies to specified versions.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to e1e45

The vulnerability remediation does not cover the AGP and Dokka dependencies it targets, so known vulnerable build-tool components remain in use. Apply the pins at plugin resolution or upgrade the plugins before merging.

Checked

• :android:dependencies at head — netty, jsoup, protobuf, jackson pins all apply
• releaseRuntimeClasspath/releaseCompileClasspath — no pinned groups, AAR unaffected
• :android:buildEnvironment — plugin classpath still Jackson 2.12.7 / woodstox 6.2.4
• All four pinned action SHAs match their tags; contents: write correct
• ubuntu-latest presets ANDROID_HOME and android-35 — no setup-android needed

Findings

• 🟠 Major · drift android/build.gradle.kts:36 — Nothing in this repo actually runs Dokka, so the reason for deferring the real fix doesn't hold
• 🟡 Minor · correctness android/build.gradle.kts:46 — These pins push versions down as well as up
• 🟡 Minor · drift gradle/libs.versions.toml:30 — Dependabot won't ever bump these four — nothing references them

CI went red on dc03ae9, and it isn't this PR's. Fixed in 582030b rather than left for someone else, since it blocks the branch.

SonarCloud failed in Setup Android SDK, step 6, before any Gradle invocation:

[command] .../cmdline-tools/16.0/bin/sdkmanager tools
Warning: Failed to find package 'tools'
Error: The process '.../sdkmanager' failed with exit code 1

android-actions/setup-android v3.2.2 installs the obsolete tools package, which Google has delisted from the SDK repository. Any repo on that version fails the same way now.

Why I'm confident it isn't the diff:

• The step runs before Gradle and never reads build.gradle.kts or libs.versions.toml — my changes can't reach it.
• The identical workflow and action SHA passed on e1e4553 eight minutes earlier; only the SDK repository contents changed in between.
• I re-ran the failed job once to rule out a flake. It reproduced exactly, so it's environmental, not transient. That's my one re-run spent — a further failure here is real.

The fix is setup-android v4.0.1 (40fd30fb), which installs only cmdline-tools. I verified against the tag's source that the bare tools install is gone.

I kept the step rather than removing it. @pandeymangg — your review noted ubuntu-latest presets ANDROID_HOME and android-35, which is true, but the later steps call sdkmanager --licenses and install platforms;android-33, and setup-android is what puts sdkmanager on PATH. Dropping it looked like it would trade this failure for a different one, so the version bump seemed the smaller move. Happy to drop the step instead if you'd rather.

This is the one part of the PR I can't verify locally — GitHub Actions only runs on GitHub. The SHA and YAML are checked; CI itself is the test.

Correcting my previous comment: the v4.0.1 bump was not the fix, and I shouldn't have expected it to be. 582030b failed identically:

[command] .../cmdline-tools/20.0/bin/sdkmanager tools
Warning: Failed to find package 'tools'

The tools install comes from the action's default input, not its code:

packages:
  default: 'tools platform-tools'

That default is byte-identical in v3.2.2 and v4.0.1, so no version of the action avoids it. I grepped the action's src/ for a hardcoded install, found none, and concluded the bump fixed it — without reading action.yml, where the actual cause was. Same mistake as the Dokka claim earlier in this PR: I verified the adjacent thing instead of the actual one.

Real fix in eef6ee4 — override the input:

with:
  packages: platform-tools

platform-tools stays because it's what the default intended minus the dead package, and "Install SDK components" installs it again below, so nothing is lost.

I kept the v4.0.1 bump rather than reverting it. It wasn't the fix, but it isn't wrong either — cmdline-tools 20.0 and a native node24 runtime, which clears the Node 20 deprecation warning the same run emitted for this action. @pandeymangg, if you'd rather keep the diff minimal, reverting to v3.2.2 with this same input override works equally well and I'll do it.

Still the one part I can't verify locally — Actions only runs on GitHub. What I can now point at is the root cause in action.yml rather than an inference.
