CVE-2026-87872

Community.general: community.general: ocapi module_utils (ocapi_command, ocapi_info) hardcode validate_certs=false with no override, enabling tls man-in-the-middle and credential disclosure

A flaw was found in the OCAPI modules (ocapi_command, ocapi_info) of the community.general Ansible collection. The shared OCAPI request helper disables TLS certificate validation on every request and the modules expose no parameter to re-enable it, while sending HTTP Basic-Auth credentials to an https endpoint. An attacker positioned on the network path between the Ansible controller and the OCAPI-managed storage/enclosure device can present any certificate, intercept the session, capture the credentials, and tamper with responses.

Community.general: community.general: memcached cache plugin deserializes untrusted pickle data from memcached, enabling cache-poisoning remote code execution on the ansible controller

A flaw was found in the memcached cache plugin of the community.general Ansible collection. Although its documentation states that records are stored in JSON format, the plugin performs no explicit serialization and relies on python-memcached, which pickles values on write and unpickles them on read. Because memcached is unauthenticated and cache keys are predictable, an attacker able to reach a network-exposed or shared memcached instance can write a crafted pickle payload that is deserialized and executed on the Ansible controller when the poisoned fact cache is next read, leading to remote code execution.

Ansible-collection-community-general: community.general: ipa_getkeytab does not set no_log on the bind_pw parameter, disclosing the ipa bind password in logs and process listings

A flaw was found in the ipa_getkeytab module of the community.general Ansible collection. The module's bind_pw parameter, used to supply the LDAP simple-bind password when retrieving a Kerberos keytab, is not declared with no_log, unlike the sibling password parameter in the same module. As a consequence, the supplied IPA/LDAP bind password is recorded in cleartext in the managed host's system journal/syslog (the module's "Invoked with" record), is included in the module's return values and verbose (-v) output, and is displayed in Automation Controller / AWX job output. The password is additionally passed on the command line to the ipa-getkeytab helper (as --bindpw <value>), exposing it in the process list to local users while the command runs. An attacker able to read these logs, job output, or the process table can obtain the directory bind credential, potentially compromising the accounts and objects that credential can access.

openvswitch: ip proto 0 triggers incorrect handling

A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.

CVE-2023-48795

ssh: Prefix truncation attack on Binary Packet Protocol (BPP)

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3, Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust.

Openstack-tripleo-common: rhosp director disables tls verification for registry mirrors

A flaw was found in the openstack-tripleo-common component of the Red Hat OpenStack Platform (RHOSP) director. This vulnerability allows an attacker to deploy potentially compromised container images via disabling TLS certificate verification for registry mirrors, which could enable a man-in-the-middle (MITM) attack.

wildfly: Wildfly management of EJB Session context returns wrong caller principal with Elytron Security enabled

This is a concurrency issue that can result in the wrong caller principal being returned from the session context of an EJB that is configured with a RunAs principal. In particular, the org.jboss.as.ejb3.component.EJBComponent class has an incomingRunAsIdentity field. This field is used by the org.jboss.as.ejb3.security.RunAsPrincipalInterceptor to keep track of the current identity prior to switching to a new identity created using the RunAs principal. The exploit consist that the EJBComponent#incomingRunAsIdentity field is currently just a SecurityIdentity. This means in a concurrent environment, where multiple users are repeatedly invoking an EJB that is configured with a RunAs principal, it's possible for the wrong the caller principal to be returned from EJBComponent#getCallerPrincipal. Similarly, it's also possible for EJBComponent#isCallerInRole to return the wrong value. Both of these methods rely on incomingRunAsIdentity. Affects all versions of JBoss EAP from 7.1.0 and all versions of WildFly 11+ when Elytron is enabled.

rhosp-director: Passwordless access for non-libvirt related services when using shared certificate authority

When libvirtd is configured by OSP director (tripleo-heat-templates) to use the TLS transport it defaults to the same certificate authority as all non-libvirtd services. As no additional authentication is configured this allows these services to connect to libvirtd (which is equivalent to root access). If a vulnerability exists in another service it could, combined with this flaw, be exploited to escalate privileges to gain control over compute nodes.

Improper i/o watch removal in tls handshake can lead to remote unauthenticated denial of service

A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service.
