Both packages arrive through transitive dependencies, so the override changes also update the resolved lockfile and Sharp's platform packages. A normal archive still extracts, and the screenshot downscaler still reads and resizes PNGs. The fix does not change the pinned evaluation harness or add a vulnerability exception. This takes the dependency update from #2867 without bundling its separate override-expiry and scheduled-notification proposals into the security patch. + +### The three numbers that matter + +These results come from OSV-Scanner 2.3.8 with the existing `.osv-scanner.toml`, and `bun test test/dependency-security.test.ts` against the original and updated lockfiles. + +| Check | Before | After | Δ | +|---|---:|---:|---:| +| Unsuppressed OSV findings | 2 | 0 | -2 | +| Security regression checks passing | 1/6 | 6/6 | +5 | +| Destination-symlink escape cases rejected | 0/2 | 2/2 | +2 | + +The two escape cases cover a symlinked file and a symlinked directory. Both now refuse the write and leave the file outside the extraction directory unchanged. The scanner's existing exceptions remain in place; zero unsuppressed findings is not a claim that every dependency is vulnerability-free. + +### What this means for users + +The installed dependency tree no longer carries these two known-vulnerable versions. The screenshot path continues to handle PNGs, while archive extraction gains the upstream boundary check without a new configuration switch. Upgrade, then run `bun install --frozen-lockfile` to install the fixed dependency set. + +### Itemized changes + +#### Security +- Upgrade the `sharp` override to 0.35.4 and `adm-zip` to 0.6.1, including the resolved Sharp platform packages. Addresses #2866. Contributed by @smsmatt in #2867. +- Add regression coverage for fixed version floors, the loaded Sharp runtime, ordinary archive extraction, and file/directory destination symlink rejection. + ## [1.87.0.0] - 2026-09-11 **`/cso` now distinguishes verified vulnerabilities from hypotheses and coverage gaps, and qualified comprehensive audits can produce replayable repair bundles without changing your working branch.** diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md index 50c854c7f..6bf656f57 100644 --- a/CONTRIBUTING.md +++ b/CONTRIBUTING.md @@ -212,6 +212,7 @@ eval files, and misses the strict classifier. No API keys needed. - **Tier-alignment invariant** (`test/e2e-tier-alignment.test.ts`) — For every self-gated `test/skill-e2e-*.test.ts` named in a touchfiles dep list, the file's `EVALS_TIER` self-gate must match its declared tier in `E2E_TIERS`. Kills the "inert demotion" class where a test is re-tiered in `touchfiles.ts` but the file still gates on the old tier and keeps running in the wrong lane. Unmapped or mixed-tier files are reported, never silently skipped. - **Catalog budget** (`test/catalog-budget.test.ts`) — Caps the aggregate discovery surface: the sum of every skill's frontmatter `name` + `description` (what every host loads at discovery, every session) must stay under 1,150 token-equivalents, with a 260-byte per-skill cap. Counting goes through the shared census in `test/helpers/skill-census.ts` (physical files vs authored skills vs registry entries — three deliberately different counts). Adding a skill? The failure message carries the re-measure + ratchet protocol. - **Context-budget ratchet** (`test/context-budget-ratchet.test.ts`) — CI ceilings on the two token ledgers the catalog budget doesn't cover: the always-on full-frontmatter aggregate and each skill's per-invocation eager tokens (SKILL.md + forced-read references), graded against `test/fixtures/context-budget.json` via `lib/context-bill.ts`. New skills fail until they have a ceiling; ceilings for removed skills must be pruned. Legitimate growth or a landed reduction: re-run `bun test/helpers/capture-context-budget.ts` and commit the refreshed fixture in the same commit, so the change is a visible decision in the diff. +- **Dependency security regressions** (`test/dependency-security.test.ts`) — Run `bun test test/dependency-security.test.ts` to check the resolved `sharp` and `adm-zip` version floors, load Sharp, verify ordinary ZIP extraction, and reject extraction through destination-file and destination-directory symlinks. The symlink cases skip Windows. These checks complement the OSV scan; they do not change its existing exceptions. ### Tier 2: E2E via `claude -p` (~$4.20/run) diff --git a/VERSION b/VERSION index 2ea29d262..e273ee6b0 100644 --- a/VERSION +++ b/VERSION @@ -1 +1 @@ -1.87.0.0 +1.87.1.0 diff --git a/agents-digest/gstack-AGENTS.md b/agents-digest/gstack-AGENTS.md index c17d43942..2c19a329a 100644 --- a/agents-digest/gstack-AGENTS.md +++ b/agents-digest/gstack-AGENTS.md @@ -1,4 +1,4 @@ -# gstack digest v1.87.0.0 — regenerate/re-copy after upgrading gstack +# gstack digest v1.87.1.0 — regenerate/re-copy after upgrading gstack Behavioral rules from gstack (https://github.com/garrytan/gstack), compressed for agent hosts without a full skill install.
