Misskey VM Misskey: CVE-2026-46713 affects Misskey 12.37.0 and later (before 2026.5.4). The issue lies in the JSON-LD signature validation and compaction process, allowing spoofed activities to be accepted as valid. The vulnerability is addressed in version 2026.5.4. Remediation: update to 2026.5...

CVE-2026-69249

python-cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 49.0.0, when resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an...

CVE-2026-69248

Cryptography (Python) prior to 49.0.0 may accept a leaf certificate with a wildcard SAN (*.example.com) when a constrained sub-CA permits foo.example.com, due to DNSConstraint::matches treating a wildcard as matching the permitted constraint. This can allow escaping to sibling names (e.g., bar.ex...

CVE-2026-69248

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 49.0.0, if an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com, python-cryptography's verifier...

CVE-2026-49132

OPNsense before 26.1.9 contains a stored cross-site scripting vulnerability that allows authenticated attackers to inject arbitrary HTML or JavaScript by embedding payloads in the certificate description field via the trust certificate API. The unsanitized description value is persisted and later...

CVE-2026-48113

Chisel is a TCP/UDP tunnel, transported over HTTP and secured via SSH. In versions prior to 1.11.5, authenticated clients can bypass --authfile ACL restrictions and tunnel traffic to arbitrary destinations reachable from the server. The ACL is enforced only during the initial handshake against...

CVE-2026-18645

A security flaw has been discovered in danpros HTMLy up to 3.1.1. This affects the function addcontent of the file /system/admin/admin.php of the component Admin Content Endpoint. Performing a manipulation of the argument oldfile results in path traversal. The attack may be initiated remotely. Th...

CVE-2026-69247

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 44.0.0 until 50.0.0, pkcs7decryptder, pkcs7decryptpem, and pkcs7decryptsmime reported the outcome of decrypting a RecipientInfo's encryptedKey in several distinguishable ways, one of which...

CVE-2026-69247

The CVE-2026-69247 entry concerns the Python cryptography package (versions 44.0.0 through 50.0.0) where pkcs7_decrypt_der, pkcs7_decrypt_pem, and pkcs7_decrypt_smime reveal distinguishable outcomes or timing when decrypting an EnvelopedData RecipientInfo encryptedKey. This creates a Bleichenbach...

CVE-2026-48113

The CVE-2026-48113 entry concerns Chisel, a TCP/UDP tunnel over SSH, where ACL restrictions provided by --authfile are bypassed on post-handshake SSH channels. Authenticated clients can open channels to arbitrary host:port destinations reachable from the server because ACL checks are performed on...

CVE-2026-48113 Chisel: ACL Bypass via Post-Handshake SSH Channel ExtraData Injection

Chisel is a TCP/UDP tunnel, transported over HTTP and secured via SSH. In versions prior to 1.11.5, authenticated clients can bypass --authfile ACL restrictions and tunnel traffic to arbitrary destinations reachable from the server. The ACL is enforced only during the initial handshake against...

CVE-2026-69245 Guzzle: Noncanonical cookie domain keeps subdomain scope

Guzzle is an extensible PHP HTTP client. Prior to 7.15.2 and 8.0.1, SetCookie::matchesDomain gives every subdomain of a cookie Domain that cookie unless SetCookie::matchesDomain recognizes the Domain as an IP literal or a numeric host, and the decision comes from the domain's own text, so two...

CVE-2026-69245

Guzzle (PHP HTTP client) prior to versions 7.15.2 and 8.0.1 is affected by a cookie-domain handling issue in SetCookie::matchesDomain(). Noncanonical domains and certain spellings (e.g., 0x7f000001, 0177.0.0.0x1, and percent-escaped forms) can cause a cookie for a given Domain to be mis-scoped to...

CVE-2026-69244 AIOHTTP: Out-of-bounds heap read in C HTTP response parser error path (malformed chunked response)

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.3, an out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response. An attacker controlled server, or possibly an accidental response, could trigg...

CVE-2026-48061

Litestar prior to v2.22.0 is affected by CVE-2026-48061: AllowedHostsMiddleware may bypass host validation by using X-Forwarded-Host when Host is absent, enabling host-header injection (e.g., password reset links, cache keys, routing decisions). The issue occurs when no reverse proxy strips X-For...

CVE-2026-69243

Affected software: AIOHTTP (async HTTP client/server for asyncio and Python). Vulnerability: HTTP request smuggling in the server-side WebSocket upgrade path due to the HTTP parser handling a WebSocket upgrade request with a body in a way that may allow trailing bytes to be misinterpreted as upgr...
