  "details": "## Summary\n\nIn versions of cryptography prior to 46.0.5, DNS name constraints were only validated against SANs within child certificates, and not the \"peer name\" presented during each validation. Consequently, cryptography would allow a peer named `bar.example.com` to validate against a wildcard leaf certificate for `*.example.com`, even if the leaf\u0027s parent certificate (or upwards) contained an excluded subtree constraint for `bar.example.com`.\n\nThis behavior resulted from a gap between RFC 5280 (which defines Name Constraint semantics) and RFC 9525 (which defines service identity semantics): put together, neither states definitively whether Name Constraints should be applied to peer names. To close this gap, cryptography now conservatively rejects any validation where the peer name would be rejected by a name constraint if it were a SAN instead.\n\nIn practice, exploitation of this bypass requires an uncommon X.509 topology, one that the Web PKI avoids because it exhibits these kinds of problems. Consequently, we consider this a medium-to-low impact severity.\n\nSee CVE-2025-61727 for a similar bypass in Go\u0027s `crypto/x509`.\n\n## Remediation\n\nUsers should upgrade to 46.0.6 or newer. \n\n## Attribution\n\nReporter: @1seal",

After the closing boundary, the parser continued processing trailing epilogue data instead of discarding it immediately. As a result, parsing time could grow with the size of crafted data placed before the first boundary or after the closing boundary.\n\n### Impact\n\nAn attacker can send oversized malformed multipart bodies that consume excessive CPU time during request parsing, reducing request-handling capacity and delaying legitimate requests. This issue degrades availability but does not typically result in a complete denial of service for the entire application.\n\n### Mitigation\n\nUpgrade to version `0.0.26` or later, which skips ahead to the next boundary candidate when processing leading CR/LF data and immediately discards epilogue data after the closing boundary.",

  "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.",
