Schwachstellen, die jetzt zählen.

Grafana: Mehrere Schwachstellen

A user with query access to a Google Cloud Monitoring data source can use its resource proxy to send requests to other Cloud Monitoring API paths with the data source's credentials, and read data from any project those credentials can reach. When the data source forwards the user's OAuth identity or uses Workload Identity Federation, the impact depends on that credential's permissions. Fixed in Google Cloud Monitoring plugin 12.6.7.

grafana: ELASTICSEARCH DATA SOURCE COULD BE USED TO SEND ARBITRARY REQUESTS TO ELASTICSEARCH

The Elasticsearch data source resource proxy forwards the request method and path to Elasticsearch using the data source's own credentials, without restricting them to the operations the plugin needs. A user who can query the data source can alter index mappings or reach other indices on the cluster. [Improper authorization / path validation]

freerdp: FreeRDP: Information disclosure via stale brush cache use-after-free

FreeRDP before 3.33.0 contains a heap use-after-free vulnerability in update_gdi_patblt(), update_gdi_polygon_cb() and update_gdi_mem3blt() that retain stale brush cache pointers. A malicious RDP server can resend CACHE_BRUSH to the same slot then send PATBLT, causing clients to read freed heap memory, disclosing data or crashing.

tinyproxy: Tinyproxy: Access control bypass via improper hostname matching

Tinyproxy through 1.11.3 contains an access control bypass vulnerability in acl_string_processing() in src/acl.c that compares only trailing hostname characters without checking DNS label boundaries. Attackers controlling the PTR record for their source IP, such as untrusted.net, can satisfy an 'Allow trusted.net' entry to use the proxy despite deny-by-default ACLs.

rack: rack: Security header bypass via unnormalized dot segments in request paths

Rack is a modular Ruby web server interface. Prior to 2.2.25, 3.1.23, and 3.2.8, Rack::Static serves a path after Utils.clean_path_info normalization but evaluates header_rules against a path that is only URL-decoded. An unauthenticated attacker can request a known file through raw or percent-encoded dot segments and receive it without path-specific security headers such as Content-Disposition or Content-Security-Policy. Applications that do not use path-specific…

rack: Rack: Security bypass and URL manipulation via invalid HTTP host headers

## Summary `Rack::Request#host_with_port`, and therefore `#base_url` and `#url`, return the raw authority string when it fails validation. An attacker-controlled `Host`, `X-Forwarded-Host`, or `Forwarded: host=` value containing characters that are not permitted in an authority is embedded verbatim in URLs generated by the application. This completes the fix for CVE-2026-34835 (GHSA-g2pf-xv49-m2h5), which made `#host` and `#hostname` return `nil` for an invalid authority but…

rack: rack: Security inspection bypass via multipart boundary parsing differential

Rack is a modular Ruby web server interface. Prior to 2.2.25, 3.1.23, and 3.2.8, Rack::Multipart::Parser.parse_boundary can skip a leading empty or quoted boundary parameter in a multipart Content-Type header and accept a later parameter. Rack can therefore parse a request body with a boundary that a conforming intermediary would not derive, allowing form fields or file uploads to reach an application without the intended proxy or web application firewall inspection. This…

aiohttp: aiohttp: Denial of Service via memory exhaustion during WebSocket frame reassembly

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, the WebSocket reader retains one bytes object for each transport read while reassembling an incomplete frame. A malicious peer can split a frame into many tiny reads so per-object overhead substantially exceeds the payload bytes allowed by max_msg_size. The condition affects a server receiving frames from a malicious client and a client receiving frames from a malicious server…

tuf: python-tuf: Unauthorized update delivery via case-insensitive path matching on Windows

python-tuf is a Python reference implementation of The Update Framework (TUF). Prior to 7.0.0, DelegatedRole._is_target_in_pathpattern in tuf/api/_payload.py uses fnmatch.fnmatch, which applies os.path.normcase before matching and makes delegation path authorization case-insensitive on Windows. When a TUF repository has path-based delegations that differ only by case and an attacker-controlled role is visited before the legitimate role, ngclient can accept an…

openscap: One-byte heap buffer overflow in sds-compose may lead to Denial-of-Service

A flaw was found in OpenSCAP. A heap-based buffer overflow can occur when processing a specially crafted Extensible Configuration Checklist Description Format (XCCDF) document using the sds-compose option. An attacker could exploit this vulnerability to corrupt memory, resulting in an application crash and a Denial of Service (DoS).

MIT Kerberos: Mehrere Schwachstellen

krb5: Unauthenticated KDC NULL pointer dereference KDC DoS via crafted PKINIT pre-auth request

MIT Kerberos: Mehrere Schwachstellen

krb5: Alteration of authentication indicators in CAMMAC container

openshift/installer: OpenShift Installer: Unconditional CSR approval during Agent-Based Installation (ABI) bootstrap

During ABI bootstrap, the bootstrap node's approve-csr.service approves and signs every CSR without identity validation. An attacker on the install network can retrieve the unauthenticated Ignition file (ports 22623/22624), extract a limited kubeconfig, submit a CSR for CN=system:admin, receive the signed certificate, and gain full cluster-admin access. Exploitable only during the narrow bootstrap window.

MIT Kerberos: Mehrere Schwachstellen

decode_sequence_of() in lib/krb5/asn.1/asn1_encode.c in MIT Kerberos 5 (aka krb5) 1.11 and later grows the decoded element array one entry at a time, which allows remote attackers to cause a denial of service (CPU consumption in the KDC) by sending an unauthenticated AS-REQ or TGS-REQ with a large number of elements in a SEQUENCE OF field over TCP.

MIT Kerberos: Mehrere Schwachstellen

krb5: kadmind: request alteration and protected information disclosure

MIT Kerberos: Mehrere Schwachstellen

The AUTH_GSSAPI handler in lib/rpc/svc_auth_gssapi.c in MIT Kerberos 5 (aka krb5) 1.5.2 and later allows remote attackers to cause a denial of service (memory exhaustion in kadmind) by sending repeated failed AUTH_GSSAPI_INIT requests. Each failed request allocates client state that is only freed after a 15-minute expiration timeout, allowing an attacker to accumulate memory faster than it is reclaimed.
