CVE-2026-66753 tiny-http 0.12.0 HTTP Response Splitting via Header Injection

tiny-http through 0.12.0 contains an HTTP header injection vulnerability that allows attackers to inject carriage return 0x0D and line feed 0x0A bytes into HTTP header values on both request and response sides due to insufficient validation in header parsing and serialization. Attackers can explo...

PT-2026-65542

Name of the Vulnerable Software and Affected Versions Rouille versions 0.3.3 through 3.6.2 Description An HTTP request smuggling issue exists where remote attackers can bypass access controls by injecting bare line feed characters 0x0A into client-supplied request header values. These values are...

httpd: Apache HTTP Server: Heap-based Buffer Overflow via malicious backend servers

A flaw was found in Apache HTTP Server. This heap-based buffer overflow vulnerability can be exploited by a malicious backend server when using ProxyPassReverseCookie directives. This could lead to a denial of service DoS condition, making the server unavailable to legitimate users...

CVE-2026-46428 lettre has TLS hostname verification disabled when using Boring TLS backend

lettre is a a mailer library for Rust. Starting in version 0.10.1 and prior to version 0.11.22, an inverted-boolean bug in lettre's boring-tls integration silently disables TLS hostname verification for callers using the default strict configuration. An on-path attacker presenting any chain-valid...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal allowing authorization bypass in the checkPrivate and WithRemote middleware in cmd/serve/restic/restic.go, where checkPrivate authorizes on the routed userID segment while WithRemote builds the backend object key fro...

PYSEC-2026-2718 Open WebUI: Authenticated users can target arbitrary configured Ollama backends via unguarded url_idx path parameter

Summary Several direct, index-addressed Ollama proxy routes accept a caller-supplied urlidx path parameter and use it as a raw index into the admin-configured OLLAMABASEURLS list. Access control on these routes validates only whether the user may use the requested model, never which backend the...

PYSEC-2026-2923 PraisonAI: SQL Injection via unvalidated `table_prefix` in 9 conversation store backends (incomplete fix for CVE-2026-40315)

The fix for CVE-2026-40315 added input validation to SQLiteConversationStore only. Nine sibling backends — MySQL, PostgreSQL, async SQLite/MySQL/PostgreSQL, Turso, SingleStore, Supabase, SurrealDB — pass tableprefix straight into f-string SQL. Same root cause, same code pattern, same exploitation...
