CVE-2026-114472

Progressive Robot hMailServer versions 6.0.0 through 6.3.6 are vulnerable to an insufficient resource pool issue in the ACME HTTP-01 challenge responder. The responder handles only one connection at a time and waits up to five seconds for a request; a remote unauthenticated attacker can hold the ...

CVE-2026-114472 Insufficient Resource Pool in hMailServer

Insufficient resource pool in the ACME HTTP-01 challenge responder of Progressive Robot hMailServer 6.0.0 through 6.3.6 allows a remote unauthenticated attacker to cause a certificate issuance or renewal to fail. When the server obtains or renews a TLS certificate over ACME it runs an HTTP-01...

CVE-2026-114472 Insufficient Resource Pool in hMailServer

Insufficient resource pool in the ACME HTTP-01 challenge responder of Progressive Robot hMailServer 6.0.0 through 6.3.6 allows a remote unauthenticated attacker to cause a certificate issuance or renewal to fail. When the server obtains or renews a TLS certificate over ACME it runs an HTTP-01...

EUVD-2026-107313

Cross-site request forgery in the REST API of Progressive Robot hMailServer 6.0.0 through 6.3.6 allows a remote attacker to make an authenticated user's browser perform a state-changing request. The REST API accepts HTTP Basic authentication and answers a browser with a Basic sign-in box; a brows...

CVE-2026-114470

Progressive Robot hMailServer versions 6.0.0 through 6.3.6 are vulnerable to a Cross-Site Request Forgery (CSRF) in the REST API . The root cause is that while the API protects cookie-based sessions, it does not apply the same protections to HTTP Basic authentication . Because browsers cache Basi...

Two critical RCEs in PHP core

Update 10/22: Added section detailing observations of in the wild exploitation and associated IOCs. Cisco Talos is tracking the disclosure of two unauthenticated remote code execution RCE flaws in PHP core, dubbed "php2shell", triggered by a plain HTTP request and exploitable before any applicati...

github.com/getkin/kin-openapi: kin-openapi: Denial of Service via unsupported HTTP methods on static paths

A flaw was found in kin-openapi. An unauthenticated remote attacker can cause a Denial of Service DoS by sending requests with unsupported or non-canonical HTTP methods to an existing static path. Because the application encounters an unhandled panic before authentication is evaluated, these...

net/http: golang: golang.org/x/net/http2: net/http: HTTP response smuggling via malformed HTTP/2 framing headers

A flaw was found in Go's net/http package. When operating as a reverse proxy, the HTTP/2 implementation does not properly validate framing-related headers in responses received from upstream servers before forwarding them to downstream HTTP/1 clients. A malicious upstream server can exploit this...

net/http: golang.org/x/net/http2: golang: net/http: Denial of Service via HTTP/2 trailer header memory exhaustion

A flaw was found in the Go net/http package. A remote attacker can trigger a Denial of Service DoS by sending HTTP/2 requests that declare an excessive number of trailer header fields. Because the server bypasses configured header limits when allocating memory for these declarations, an attacker...

net/http: net/http/internal/http2: golang: golang.org/x/net/http2: golang: flow control limit bypass via double refund in HTTP/2 server

A flaw was found in Go's HTTP/2 server implementation. A remote attacker can bypass connection-level flow control limits—mechanisms that regulate incoming network data—potentially causing excessive memory consumption and a Denial of Service DoS. This issue occurs because the server improperly...

net/http: golang: net/http: HTTP request smuggling via improper handling of HTTP/1 CONNECT responses

A flaw was found in Go's net/http package. When an HTTP server sends a successful response to an HTTP/1 CONNECT request without taking raw control of the connection, it improperly continues to process incoming data as standard HTTP requests instead of establishing a tunnel. A remote attacker can...

net/http: golang: golang: Denial of Service via crafted HTTP Range headers

A flaw was found in the Go net/http package. A remote attacker can cause a Denial of Service DoS by sending an HTTP request containing a Range header with a large number of small byte ranges. When the server processes these ranges while serving content, it consumes an excessive amount of CPU...

net/http: golang: golang: Cross-user response poisoning via desynchronized HTTP CONNECT connections

A flaw was found in Go's net/http package. When an HTTP CONNECT request with a request body is rejected by a server, the client transport can desynchronize the connection before returning it to the shared idle pool. In shared reverse proxy environments, a remote attacker can exploit this issue to...

net/http: net/http/internal/http2: golang.org/x/net/http2: net/http: Denial of Service via excessive HTTP/2 SETTINGS frames

A flaw was found in the Go net/http package. This flaw allows a remote attacker to cause a Denial of Service DoS by triggering excessive CPU consumption on an affected client or server. By opening a large number of HTTP/2 streams and repeatedly sending small configuration SETTINGS frames that...

net/http: net/http/internal/http2: golang: golang.org/x/net/http2: net/http: Denial of Service via concurrent HPACK encoder modification

A flaw was found in Go's net/http package. A remote attacker can cause a Denial of Service DoS by crashing the HTTP/2 server. Due to missing synchronization, the server concurrently modifies its HPACK HTTP/2 header compression encoder when encoding response headers while processing incoming table...
