{ "url": "http://public2.vulnerablecode.io/api/vulnerabilities/24981?format=api", "vulnerability_id": "VCID-62r9-cvp9-tfbg", "summary": "go-git missing validation decoding Index v4 files leads to panic\n### Impact\n\n`go-git`’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing.\n\nThis issue only affects Git index format version 4. Earlier formats (`go-git` supports only `v2` and `v3`) are not vulnerable to this issue.\n\nAn attacker able to supply a crafted `.git/index` file can cause applications using go-git to panic while reading the index. If the application does not recover from panics, this results in process termination, leading to a denial-of-service (DoS) condition.\n\nExploitation requires the ability to modify or inject a Git index file within the local repository in disk. This typically implies write access to the `.git` directory.\n\n### Patches\n\nUsers should upgrade to `v5.17.1`, or the latest `v6` [pseudo-version](https://go.dev/ref/mod#pseudo-versions), in order to mitigate this vulnerability.\n\n### Credit\n\ngo-git maintainers thank @kq5y for finding and reporting this issue privately to the `go-git` project.", "aliases": [ { "alias": "CVE-2026-33762" }, {
