What's Changed

• Breaking changes

  • Linters can no longer be run via a sibling Docker image at runtime. The cli_docker_image, cli_docker_image_version and cli_docker_args descriptor properties (and the matching <LINTER>_DOCKER_IMAGE_VERSION variable) have been removed, and MegaLinter no longer mounts /var/run/docker.sock (in mega-linter-runner, the GitHub Action action.yml files, and the Docker daemon previously bundled in flavor images). This closes the host-privilege escalation surface that the mounted Docker socket exposed. The only linter that used this mechanism was SWIFT_SWIFTLINT, now installed natively (see below). (#8216)
  • SWIFT_SWIFTLINT is now installed from the static swiftlint-static binary instead of running the ghcr.io/realm/swiftlint container. It runs natively on the Alpine image with no Docker socket required. SourceKit-dependent rules are disabled in this build and reported to the console when encountered; pure-syntax style rules are unaffected. (#8216)
  • @eslint/eslintrc shim removed from JavaScript/TypeScript/JSX/TSX Docker images (was only needed for legacy FlatCompat); MegaLinter's bundled test fixtures use native flat config. (#7869)
  • ESLint linters now force migration off .eslintrc.*: JAVASCRIPT_ES, TYPESCRIPT_ES, JSX_ESLINT, TSX_ESLINT activate when they find any eslint.config.* or any deprecated .eslintrc.* / package.json#eslintConfig. In the legacy case the linter does not call ESLint at all — it emits a single hard failure with a migration message so the build stays red until the config is migrated to flat config. See the ESLint flat-config migration guide. To opt out, set DISABLE_LINTERS or DISABLE to exclude the affected linter/descriptor. (#7869)
  • JSON_ESLINT_PLUGIN_JSONC removed: upstream bug ota-meshi/eslint-plugin-jsonc#328 blocks ESLint v10 compatibility and will not be fixed. Use JSON_JSONLINT, JSON_PRETTIER, or JSON_V8R for JSON validation instead. (#7869)

• Core

  • New linter descriptor property common_linter_errors: declare known non-lint failure patterns (config issue, remote service down, missing credentials…) and the guidance message shown to users, directly in YAML — no custom Python class needed. (#7907)
  • Skipped-linters summary now explains why a linter was skipped by an activation rule, including the variable to set to activate it (e.g. MARKDOWN_RUMDL: MARKDOWN_DEFAULT_STYLE=markdownlint (set MARKDOWN_DEFAULT_STYLE=rumdl to activate)), fixing #8017.

• New linters

  • Add betterleaks linter for repository secrets scanning — successor to gitleaks with higher recall (98.6% vs 70.4%), lower false-positive rates, and 4–5× faster scanning via BPE-based detection and CEL filter expressions (#8186)

• Disabled linters

  • SALESFORCE_SFDX_SCANNER_APEX, SALESFORCE_SFDX_SCANNER_AURA and SALESFORCE_SFDX_SCANNER_LWC — disabled because sfdx-scanner 4.12.0 crashes on Node.js 22+ (TypeError: Cannot read properties of undefined (reading 'prototype'), caused by the removal of SlowBuffer.prototype), which is shipped with Alpine 3.24. These linters were already deprecated; use the SALESFORCE_CODE_ANALYZER_APEX / SALESFORCE_CODE_ANALYZER_AURA / SALESFORCE_CODE_ANALYZER_LWC variants instead (#8080).

• Deprecated linters

  • REPOSITORY_GITLEAKS — deprecated in favour of REPOSITORY_BETTERLEAKS (same author, fully compatible config, significantly better detection). Will be removed in the next major release. Disable it by adding REPOSITORY_GITLEAKS to DISABLE_LINTERS in your .mega-linter.yml. (#8186)

• Removed linters

  • JSON_ESLINT_PLUGIN_JSONC — permanently broken by upstream bug (see Breaking changes) (#7869)

• Linters enhancements

  • REPOSITORY_CHECKOV: in pull-request mode, scan only the files modified in the PR instead of the whole repository (#7119)

• Fixes

  • REPOSITORY_BETTERLEAKS: default scan now runs in filesystem (dir) mode instead of auto-switching to git-history (git) mode when a git repository is detected. betterleaks does not read the global git safe.directory config, so git mode failed with fatal: detected dubious ownership in repository in CI environments (e.g. GitHub Actions /github/workspace). Git-history mode is still used for the opt-in REPOSITORY_BETTERLEAKS_PR_COMMITS_SCAN feature. (#8186)
  • REPOSITORY_BETTERLEAKS: added --verbose so detected findings (file, line and rule) are reported instead of only the leaks found: N summary, matching gitleaks behavior. Secret values stay redacted via --redact. (#8186)
  • REPOSITORY_OSV_SCANNER: exit code 128 ("No package sources found") is now treated as a clean pass instead of a failure — osv-scanner returns this code when the repo contains no lockfiles/manifests/SBOMs, which is not a vulnerability finding (#7917).
  • Fix intermittent ansible-lint load-failure[not-found] error on github_conf/branch_protection_rules.json caused by a race condition with checkov running in parallel. Checkov's transient GitHub-conf directory is now written to a hidden path (.megalinter_github_conf) that project-mode linters skip, eliminating the conflict (#8092).
  • Complete the Alpine 3.24 upgrade across the whole image and fix how alpine version is detected. Docker images now build on the python:3.14-alpine3.24 base image (#8080).
  • Avoid DeprecationWarning / future breakage on Python 3.14 by no longer passing count and flags as positional arguments to re.sub (#8211).
  • Exclude REPORT_OUTPUT_FOLDER from linting when configured as an absolute path inside the workspace (e.g. /tmp/lint/megalinter-reports), fixing #7845.
  • Fix command injection in Roslynator linter (DOTNET_ROSLYNATOR) where a crafted .csproj filename could break out of dotnet restore arguments and execute arbitrary shell commands. The command is now invoked via argv list instead of a shell string. Reported by Francesco Sabiu. (#7857)
  • Fix IndexError when building the single-linter Docker image for a linter whose activation depends on a file (e.g. SPELL_VALE requires .vale.ini): python -m megalinter.run --linterversion now bypasses activation filtering since the per-linter image is built for that linter unconditionally.
  • Fix make bootstrap appearing to hang because exported Make color variables re-evaluated tput during recursive make invocations. (#8090)
  • Allow MegaLinter containers to run in an opt-in non-root mode matching the host UID:GID on POSIX systems, avoiding root-owned generated files on the host (#1975).
  • Restore missing examples in the Dart descriptor that were dropped from the generated documentation (#7913).

• Reporters

  • Update Bitbucket pipeline generator template to trigger builds on pull requests from any branch, by @​yermulnik in oxsecurity/megalinter#7421

• Doc

  • Add pnpm installation and usage documentation for JavaScript and TypeScript linters (#8177)
  • Update Docker pull counters in README badges and flavors-stats.json with latest ghcr.io stats
  • Bump peter-evans/create-pull-request to v8 in the documented workflow examples (#8089)

  • Fix per-linter Docker images being published single-arch. The BETA and RELEASE linter workflows split each linter into independent per-platform jobs that all pushed the same tag (:beta, :v9, :vX.Y.Z, :latest), so the last push won and overwrote the other architecture. They now push each platform by digest and a dedicated merge job assembles a proper multi-arch manifest list per linter, restoring linux/amd64 + linux/arm64 support for megalinter-only-* images.
