Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package manifest contains repeated, unusually specific review-directed defenses of package behaviors, which indicates an attempt to influence security review. The inspected runtime code appears consistent with the package’s stated Theia/GLSP purpose, but that does not remove the malicious review manipulation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-11-02T02:07:29.482Z - **Finished:** 2026-11-02T02:07:57.604Z - **Download time:** 501 ms - **Static scan time:** 227 ms - **AI review time:** 27393 ms - **Total time:** 28122 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Review-directed package metadata attempts to preempt scrutiny of package behavior; no separate runtime attack was identified. - **Trigger:** Reviewing package.json; the text is present in the published manifest. - **Impact:** Could manipulate automated or human review into overlooking package risks. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-11-02T02:07:57.604Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Nonstandard // metadata fields provide unsolicited defenses of the exports, peer dependency, prepack hook, and CSS import. - **Attack narrative:** The manifest contains multiple unsolicited // fields that explain away review-relevant package behavior, including the prepack hook and module imports. This is deliberate review-directed manipulation. The inspected JavaScript and stylesheet show ordinary package functionality, with no separate runtime attack identified. - **Rationale:** The package manifest contains repeated, unusually specific review-directed defenses of package behaviors, which indicates an attempt to influence security review. The inspected runtime code appears consistent with the package’s stated Theia/GLSP purpose, but that does not remove the malicious review manipulation. - **Files touched:** package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 86.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json contains nonstandard // fields that argue how reviewers should interpret the exports, peer dependency, prepack hook, and stylesheet side effect., The prepack note explicitly dismisses install concerns, while the other notes frame the package’s behavior as harmless; together these are review-directed attempts to preempt scrutiny. - **Evidence against:** The declared lifecycle scripts contain no install, preinstall, or postinstall hook., The inspected entry points export Theia/GLSP modules, and the diagram widget imports the package’s loading stylesheet; no unrelated runtime action was identified. ## Affected versions and remediation This report applies to @hydranium/glsp-client-theia@1.0.0-next.391. - Avoid installing @hydranium/glsp-client-theia@1.0.0-next.391. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** style/diagram-loading.css - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```css stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 1 ``` ### 3. High: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 86.0% - **Path:** package.json - **Public source:** [View source]() package.json contains nonstandard // fields that argue how reviewers should interpret the exports, peer dependency, prepack hook, and stylesheet side effect. Public source snippet (untrusted): ```json "//exports": "The stylesheet key is an ASSET entry, not a module subpath, and it is spelled as the exact filename rather than `./style/*` so nothing becomes reachable automatically — the same no-wildcard property every other key here has. It exists because the widget's own import is package-RELATIVE, which `exports` does not gate, so the map's silence broke nobody inside the package while blocking every adopter who wants to `@import` the sheet, re-bundle it or override it by specifier; that failure reads as \"not exported under the conditions\" rather than as a missing entry. `tsc` emits n ``` ### 4. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 86.0% - **Path:** package.json - **Public source:** [View source]() The prepack note explicitly dismisses install concerns, while the other notes frame the package’s behavior as harmless; together these are review-directed attempts to preempt scrutiny. Public source snippet (untrusted): ```json "//prepack": "The publish guard, a `prepack` rather than a `prepare`: `prepack` runs only when a tarball is made (`npm pack`, `npm publish`) and never on install, so it cannot break the install it has no business touching. What it defends against: `files` lists `lib`, `lib` is gitignored, and a `files` entry matching nothing is skipped SILENTLY — so `npm publish` from an unbuilt tree emits a tarball of `src` and ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 11 - **Development dependencies:** 18 - **Published dependency-graph edges:** 11 ### Published dependency entries - @eclipse-glsp/client ^2.7.0 (PeerDependency) - @eclipse-glsp/theia-integration ^2.7.0 (PeerDependency) - @hydranium/client-theia 1.0.0-next.391 (PeerDependency) - @hydranium/glsp-client 1.0.0-next.391 (PeerDependency) - @hydranium/protocol 1.0.0-next.391 (PeerDependency) - @theia/core ^1.70.0 (PeerDependency) - @theia/process ^1.70.0 (PeerDependency) - @theia/workspace ^1.70.0 (PeerDependency) - inversify ^6.1.3 (PeerDependency) - snabbdom ~3.5.1 (PeerDependency) - vscode-jsonrpc ^9.0.0 (PeerDependency) ## Package metadata - **Package:** @hydranium/glsp-client-theia - **Ecosystem:** npm - **Version:** 1.0.0-next.391 - **License:** MIT - **Version published:** 2026-11-02T02:06:08.921Z - **Package first seen:** 2026-09-09T10:04:40.323Z - **Package last seen:** 2026-11-04T11:52:07.117Z - **Known versions:** 165 - **Latest version:** 1.0.0-next.421 - **Appeal under review:** No - **Description:** Theia-coupled client primitives for GLSP heads built on @hydranium/glsp-server.
