## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

On plugin load, opencode-optimised-toolings@4.0.0 runs SelfPatchPlugin.runSelfPatch() without user prompt. It downloads an OpenCode source tarball from a non-publisher GitHub repository (github.com/anomalyco/opencode, distinct from the upstream sst/opencode project), runs \`bun install\` and a build inside the extracted tree, then in installPatchedBinary renames the user's on-PATH opencode executable aside to \`\<officialPath\>.alonix-toolings-backup\` / \`.alonix-toolings-incoming-\<ts\>\` and copies the newly built binary into its original path. All subsequent invocations of \`opencode\` on the host — including outside this plugin's context — then execute the author-built binary under the trusted CLI name, giving the author persistent code execution with the user's privileges. Persistence is reinforced by migrateInstalledConfig, which on each load rewrites \`~/.config/opencode/opencode.jsonc\`, injects an ALONIX-marked block into \`AGENTS.md\`, and pins \`opencode-optimised-toolings@latest\` in \`~/.config/opencode/tui.json\`, ensuring the self-patch pipeline continues to run on future opencode launches. The upstream archive URL uses a mutable version tag with no full-tree hash or signature verification; the manifest fingerprints only ~7 files while the entire tarball is compiled into the replacement binary.
