  "details": "## Vulnerability Summary\n\nThe `public_key_from_numbers` (or `EllipticCurvePublicNumbers.public_key()`), `EllipticCurvePublicNumbers.public_key()`, `load_der_public_key()` and `load_pem_public_key()` functions do not verify that the point belongs to the expected prime-order subgroup of the curve.\n\nThis missing validation allows an attacker to provide a public key point `P` from a small-order subgroup.  This can lead to security issues in various situations, such as the most commonly used signature verification (ECDSA) and shared key negotiation (ECDH). When the victim computes the shared secret as `S = [victim_private_key]P` via ECDH,  this leaks information about `victim_private_key mod (small_subgroup_order)`. For curves with cofactor \u003e 1, this reveals the least significant bits of the private key.  When these weak public keys are used in ECDSA , it\u0027s easy to forge signatures on the small subgroup.\n\nOnly SECT curves are impacted by this.\n\n## Credit\n\nThis vulnerability was discovered by:\n- XlabAI Team of Tencent Xuanwu Lab\n- Atuin Automated Vulnerability Discovery Engine",

  "details": "### Summary\n\n`TemplateLookup.get_template()` is vulnerable to path traversal when a URI starts with `//` (e.g., `//../../../secret.txt`). The root cause is an inconsistency between two slash-stripping implementations:\n\n- `Template.__init__` strips **one** leading `/` using `if`/slice\n- `TemplateLookup.get_template()` strips **all** leading `/` using `re.sub(r\"^\\/+\", \"\")`\n\nWhen a URI like `//../../../../etc/passwd` is passed:\n1. `get_template()` strips all `/` \u2192 `../../../../etc/passwd` \u2192 file found via `posixpath.join(dir_, u)`\n2. `Template.__init__` strips one `/` \u2192 `/../../../../etc/passwd` \u2192 `normpath` \u2192 `/etc/passwd`\n3. `/etc/passwd`.startswith(`..`) \u2192 `False` \u2192 **check bypassed**\n\n### Impact\n\nArbitrary file read: any file readable by the process can be returned as rendered template content when an application passes untrusted input directly to `TemplateLookup.get_template()`.\n\nNote: this is exploitable at the library API level. HTTP-based exploitation is mitigated by Python\u0027s `BaseHTTPRequestHandler` which normalizes double-slash prefixes since CPython gh-87389. Applications using other HTTP servers that do not normalize paths may be affected.\n\n### Fix\n\nChanged `Template.__init__` to use `lstrip(\"/\")` instead of stripping only a single leading slash, so both code paths handle leading slashes consistently.",

The fix switches the prompt template renderer to a sandboxed environment that blocks the attributes this attack relies on.\n\nLiteLLM recommends upgrading to `1.83.7-stable` or later.\n\n### Workarounds\nIf upgrading is not immediately possible:\n\n1. Block `POST /prompts/test` at your reverse proxy or API gateway.\n2. Review and rotate API keys that should not have access to prompt management routes.",
