- Around line 20-28: Protect the osv-scanner configuration used by the
pull_request audit from changes introduced by the PR: require maintainer review
for osv-scanner.toml via repository ownership controls, or make the workflow
load the trusted configuration from the base branch instead of the merge commit.
Preserve the existing recursive scan behavior in the osv-scanner-action step.
- Around line 24-28: Remove the --allow-no-lockfiles option from the scan-args
configuration so the supply-chain audit fails when no supported lockfile,
including uv.lock, is present. Keep the recursive scan, table format, and
repository path arguments unchanged.
- Around line 22-28: Atualize o workflow de auditoria para usar
google/osv-scanner-action/.github/workflows/osv-scanner-reusable.yml por SHA
fixo, substituindo o uso direto de osv-scanner-action. Remova --format=table de
scan-args, preserve os demais argumentos necessários e defina fail-on-vuln como
true explicitamente.
- Around line 20-22: Fix the supply-chain audit workflow by pinning
actions/checkout and the OSV-Scanner reference to the specified immutable commit
SHAs, and disable checkout credential persistence via persist-credentials:
false. Replace the direct osv-scanner-action invocation with the official
reusable workflow, also pinned by immutable SHA; retain permissions contents:
read and add no secrets or cache.

site:docs.github.com actions checkout pull_request default ref merge commit workflow
💡 Result:
When using the actions/checkout action in a workflow triggered by the pull_request event, the default behavior is to check out the merge commit of the pull request [1][2]. Specifically, for open and mergeable pull requests, GitHub creates a synthetic merge branch—represented by the ref refs/pull/<pull_request_number>/merge—which combines the base branch with the pull request's head branch [2][3]. Because actions/checkout uses the github.ref context by default, and github.ref is set to this merge ref for pull_request events, the action automatically checks out this merge commit [2][3]. This ensures your CI tests and builds run against the actual code that would result from merging the pull request [2]. In contrast, if you use the pull_request_target event, the default behavior of actions/checkout is different because the workflow and the github.ref context are taken from the base repository's default branch rather than the pull request's merge branch [1][4]. This is a security-focused design intended to prevent untrusted code from a fork from being automatically executed with elevated permissions [1][5]. If you need to check out the pull request code specifically while using pull_request_target, you must explicitly specify the ref (e.g., using ref: ${{ github.event.pull_request.head.sha }} or ref: refs/pull/${{ github.event.pull_request.number }}/merge) and, in certain cases, handle security implications carefully [1][4].

site:google.github.io osv-scanner osv-scanner.toml ignore vulnerabilities configuration
💡 Result:
To ignore vulnerabilities in OSV-Scanner, you can use an osv-scanner.toml configuration file. There are two primary methods for ignoring vulnerabilities depending on your requirements: ignoring specific vulnerability IDs or ignoring entire packages [1][2]. 1. Ignoring Vulnerabilities by ID To ignore a specific vulnerability, add an entry under the [[IgnoredVulns]] key in an osv-scanner.toml file located in the same directory as the lockfile being scanned [1][3]. You can optionally include an expiry date or a reason for the exclusion [1]. [[IgnoredVulns]] id = "CVE-YYYY-NNNN" # ignoreUntil = 2026-12-31 # Optional expiry date reason = "Reason for ignoring this vulnerability" Ignoring a vulnerability ID will also automatically ignore any aliases associated with it [1]. 2. Ignoring Packages or Overrides For broader control, you can use the [[PackageOverrides]] key to ignore packages entirely or specifically ignore their vulnerabilities [1][2]. [[PackageOverrides]] # Example: Ignore this package completely (vulnerabilities and license violations) # name = "package-name" # ignore = true # Example: Ignore only vulnerabilities for this package # name = "package-name" # vulnerability.ignore = true Configuration File Placement and Usage By default, placing an osv-scanner.toml file in a directory applies that configuration only to files within that specific directory; it does not propagate to child directories [1]. To apply a configuration globally, you can use the --config flag when running the scan, which overrides any local osv-scanner.toml files [1][4]: osv-scanner scan --config /path/to/global-config.toml Note that while OSV-Scanner respects.gitignore files by default (unless --no-ignore is used), PackageOverrides are the recommended way to handle specific package exclusions within the scanner configuration itself [5].

OSV-Scanner v2.5.1 supported lockfiles pyproject.toml --allow-no-lockfiles google/osv-scanner-action
💡 Result:
OSV-Scanner does not natively support pyproject.toml as a direct manifest file for dependency analysis [1][2]. While it supports many Python ecosystems that utilize pyproject.toml—such as Poetry (poetry.lock), PDM (pdm.lock), and others (pylock.toml, uv.lock)—it requires a corresponding lockfile to perform vulnerability scanning [1]. The --allow-no-lockfiles flag is a valid argument for the OSV-Scanner CLI, introduced in version 2.0.3 [3]. This flag is used to suppress warnings or errors that occur when the scanner fails to detect any supported lockfiles in the target directory [3][4][5]. When using the google/osv-scanner-action in GitHub CI/CD, you can pass this flag by using the scan-args input in your workflow configuration [6][7][8]. Because the action reuses the underlying OSV-Scanner CLI, it will honor the --allow-no-lockfiles argument if provided: jobs: osv-scan: uses: google/osv-scanner-action/.github/workflows/osv-scanner-reusable.yml@main with: scan-args: "--allow-no-lockfiles" Please note that even with this flag, if no supported lockfile is present, the scanner will not be able to identify your project's dependencies to perform a vulnerability check against the OSV database [9]. If you are relying on pyproject.toml for dependency management, ensuring a supported lockfile is generated and present in your repository is necessary for effective scanning [1].

site:github.com/google/osv-scanner discussion 1529 allow-no-lockfiles exit code no lockfiles
💡 Result:
In OSV-Scanner, exit code 128 is returned when no packages (or lockfiles) are found during a scan [1][2]. This behavior is designed to alert users to potential misconfigurations, such as when a directory is scanned but no recognized dependency files are present [2]. To suppress this error and prevent the process from exiting with 128, you can use the --allow-no-lockfiles flag [3][4]. This flag was introduced to address feedback from the community regarding CI/CD workflows failing when no lockfiles were detected [3][4]. If you are using the OSV-Scanner GitHub Action, note that older versions may require manual handling of this exit code [3], while newer versions support the --allow-no-lockfiles flag to explicitly handle these cases [4][5]. If this flag is omitted, the tool may issue a warning in CI environments recommending its use [4][5]. The discussion mentioned in your query (GitHub Discussion #1529) relates to general feedback for the OSV-Scanner v2 beta and includes context on improvements to dependency extraction and workflow behavior [3][6][7].

Remova --allow-no-lockfiles
uv.lock é suportado e existe no repositório. Porém, essa opção permite uma auditoria bem-sucedida sem analisar dependências se um pull request remover ou renomear uv.lock. Remova a opção ou exija explicitamente pelo menos um arquivo suportado.

In @.github/workflows/supply-chain-audit.yml around lines 24 - 28, Remove the
--allow-no-lockfiles option from the scan-args configuration so the supply-chain
audit fails when no supported lockfile, including uv.lock, is present. Keep the
recursive scan, table format, and repository path arguments unchanged.

Auditoria permanente de supply chain (Fase 3)
Complemento da auditoria de 2026-08-22. Sem alteração de código ou dependências.
O que entra
.github/workflows/supply-chain-audit.yml: osv-scanner em PR, push na branch padrão e semanalmente; falha em qualquer vulnerabilidade conhecida que não esteja documentada emosv-scanner.toml.osv-scanner.toml: 3 vulnerabilidade(s) do backlog aceito (fix exige major ou não existe), cada uma com motivo e data de reavaliação (2026-11-22). O CI nasce verde e bloqueia só o que for novo..github/dependabot.yml(se não existia): atualizações semanais agrupadas, PRs limitados a 5.Arquivos
Achados novos (não corrigidos aqui, só CI)
Notas
Worktree criado fresco a partir de origin/main (branch ci/supply-chain-audit) em /Users/nikolas/Projects/mcp-fiscal-brasil-sc3. Workflow copiado do template com on.push.branches ajustado para [main] (default real do repo). .github/dependabot.yml JA EXISTIA (pip + github-actions) e foi mantido intocado conforme regra "se ja existir, nao tocar" (item 3 da tarefa nao se aplicou). Unico lockfile no repo e uv.lock (npm-wrapper/ tem package.json mas sem package-lock.json, entao nao e escaneado). osv-scanner (binario /opt/homebrew/bin/osv-scanner) achou 3 vulnerabilidades (2 em pymdown-extensions, 1 em setuptools), todas com aliases PYSEC/GHSA; osv-scanner.toml usa os IDs GHSA (osv-scanner resolve aliases automaticamente, confirmado empiricamente: "GHSA-xxxx and N aliases have been filtered out"). YAML e TOML validados com sucesso (YAML via uv run --with pyyaml, ja que o Python do sistema nao tem PyYAML; TOML via tomllib). Scan final "osv-scanner scan source --recursive --format=table ./" termina com exit 0. Commit unico criado, sem push, git status --porcelain limpo. Hook local prompt-injection-detector bloqueou a primeira tentativa de commit por falso positivo na palavra "bypass" dentro
