CVE-2026-63476 1 Isomorphic-git 1 Isomorphic-git 2026-11-04 4.3 Medium
isomorphic-git is a pure JavaScript implementation of Git for Node.js and browsers. Prior to 1.38.6, isomorphic-git reads a server-controlled targetSize while applying a packfile delta in src/utils/applyDelta.js and passes it without a bound to Buffer.alloc(targetSize). A malicious or man-in-the-middle-controlled remote can send one delta header that causes git.clone() or git.fetch() to allocate approximately 2 GB before validating the actual delta output. GitPackIndex.fromPack swallows the later size-mismatch error, so a host with sufficient memory may retain the resource waste without a visible failure, while containers, serverless functions, and small virtual machines may terminate. Node.js heap limits do not mitigate the off-heap Buffer allocation. This issue is fixed in version 1.38.6.
CVE-2026-63478 1 Isomorphic-git 1 Isomorphic-git 2026-11-03 5.3 Medium
isomorphic-git is a pure JavaScript implementation of Git for Node.js and browsers. Prior to 1.38.6, isomorphic-git's tree parser in src/models/GitTree.js accepts a standalone .. tree-entry name because it rejects only path separators. During clone or checkout from a malicious or man-in-the-middle-controlled non-GitHub remote, nested .. entries can escape the working-tree root and write files at attacker-selected parent paths on any host-backed fs provider. The arbitrary file write can overwrite startup or configuration files and lead to code execution. GitHub-hosted trees are not a direct source because GitHub rejects .. entries during repository integrity checks. This issue is fixed in version 1.38.6.
CVE-2021-30483 2 Isomorphic-git, Redhat 3 Isomorphic-git, Rhev Hypervisor, Rhev Manager 2024-11-21 5.3 Medium
isomorphic-git before 1.8.2 allows Directory Traversal via a crafted repository.
CVE-2021-23664 1 Isomorphic-git 1 Cors-proxy 2024-11-21 8.6 High
The package @isomorphic-git/cors-proxy before 2.7.1 are vulnerable to Server-side Request Forgery (SSRF) due to missing sanitization and validation of the redirection action in middleware.js.
