CVE-2026-85518

Openscap: openscap: arbitrary file write via path traversal in source datastream decomposition

A flaw was found in OpenSCAP. When decomposing a Source DataStream (SDS) file, the application does not properly validate relative file path attributes, leading to a path traversal vulnerability. An attacker can exploit this flaw by tricking a user or automated system into decomposing a crafted datastream containing directory traversal sequences. Successful exploitation allows unauthorized file creation or modification outside the intended target directory with the permissions of the executing process.

Ansible-pylibssh: accepts a changed ssh host key when host_key_auto_add is enabled

A host key verification flaw was found in ansible-pylibssh and in the ansible.netcommon libssh connection plugin. When trust-on-first-use is enabled (host_key_auto_add on the libssh connection plugin, or AutoAddPolicy in ansible-pylibssh), a host that is already present in known_hosts but now presents a different key is accepted without warning. The pylibssh Session.verify_knownhost() method passes the SSH_KNOWN_HOSTS_CHANGED and SSH_KNOWN_HOSTS_OTHER states to the same missing_host_key() policy hook used for unknown hosts, and the bundled AutoAddPolicy/RejectPolicy classes (as well as ansible.netcommon's MyAddPolicy, which is modeled on paramiko's AutoAddPolicy) therefore add the changed key and continue the connection rather than aborting as paramiko's BadHostKeyException path would. As a result the controller authenticates to the substitute host, runs the play there, and appends the new key to known_hosts, which can disclose connection credentials to an attacker performing a machine-in-the-middle attack. Default configurations (host_key_checking enabled, host_key_auto_add unset) are not affected; non-interactive runs fail closed.

Busybox: cpio hardlink target not sanitized under feature_path_traversal_protection

A flaw was found in BusyBox. When extracting files using the cpio utility with path traversal protection enabled, hardlink target paths are not properly sanitized. By tricking a user or automated process into extracting a crafted archive, an attacker can create hardlinks that point to files outside the intended extraction directory. This issue may allow an attacker to modify or overwrite arbitrary files outside the target directory during subsequent extraction operations.

Xdgmime: heap-based buffer overflow in _xdg_mime_magic_parse_magic_line() in xdgmimemagic.c

A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in _xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2 bytes, resulting in an application crash or memory corruption.

A flaw was found in the deployment-operation family of WildFly Core. Certain handlers, such as upload-deployment-url, lack proper sensitivity classification, allowing an administrator with the restricted "Maintainer" role to read sensitive configuration files. This can lead to the exfiltration of credentials and full administrative control (SuperUser) of the server.

Awx: unauthenticated debug endpoints trigger scheduler operations

A flaw was found in AWX. The debug API endpoints (/api/debug/task_manager/, /api/debug/dependency_manager/, /api/debug/workflow_manager/) are registered unconditionally in the URL configuration and use AllowAny permission class with _ignore_model_permissions=True. This allows an unauthenticated remote attacker to repeatedly invoke scheduler operations that acquire database advisory locks and open transactions, potentially leading to resource exhaustion and degraded service availability.

A flaw was found in GStreamer's MXF demuxer. When an application processes a crafted MXF file, an off-by-one bounds check can allow a one-byte write past the logical end of a temporal offset array. This may corrupt memory and cause the application to crash. The extent of the impact has not been demonstrated by a runtime test.

A flaw was found in GStreamer's gst-plugins-bad MPEG Program Stream demuxer and resindvd DVD-playback plugin. The PES header parsers do not adequately check remaining data before reading timestamps and optional header fields. Opening a specially crafted MPEG Program Stream file can cause an out-of-bounds read and potentially crash the application, resulting in a denial of service.

Cockpit: cockpit: local privilege escalation via insecure symlink handling in public key addition helper

A flaw was found in Cockpit. A local authenticated user with control over a target account's home directory can exploit a privileged symlink dereference vulnerability in the `ssh-add-public-key.sh` helper. When this helper runs with elevated privileges, it can be tricked into following attacker-controlled symlinks within the `.ssh` or `authorized_keys` paths. This allows the attacker to arbitrarily change file ownership and modes, potentially leading to local privilege escalation and impacting the integrity, confidentiality, and availability of the system.

CVE-2026-71367

Awx: websocket broadcast groups leak cross-organization job metadata

An incorrect authorization vulnerability was found in AWX's WebSocket consumer. The consumer_access() function only enforces access controls for object-level event groups (job_events, workflow_events, ad_hoc_command_events) but does not restrict subscriptions to global broadcast groups such as 'jobs-status_changed'. When an authenticated user subscribes to a global broadcast group, the server accepts the subscription without verifying that the user has permission to view the associated resources. In multi-organization deployments, this allows a low-privilege user in one organization to receive real-time job status metadata from all organizations, including job IDs, status transitions, timestamps, and infrastructure topology details such as instance group names, bypassing the organization isolation enforced by the REST API.

Rpm: command injection in `rpmbuild -t*` (`gettarspec`) via unescaped tarball path

A flaw was found in rpm. An attacker can exploit a command injection vulnerability by influencing the path or filename of a tarball processed by `rpmbuild -t*` to include shell metacharacters. This is particularly relevant in automated build or continuous integration (CI) workflows that ingest externally supplied artifact names. Successful exploitation allows for arbitrary command execution with the privileges of the build user, which could lead to information disclosure or disruption of the build environment.

Rpm: rpmbuild gettarspec() crafted tar member name → macro injection

A vulnerability was found in RPM's rpmbuild tarball processing. When processing a crafted source archive, the getTarSpec() function in tools/rpmbuild.cc passes an attacker-controlled tar archive member name to rpmExpand() as part of a %{basename:...} macro expression. A specially crafted .spec member name can therefore inject RPM macros, including Lua expressions, resulting in arbitrary code execution with the privileges of the user running rpmbuild. This can be exploited when a victim or automated build system processes an attacker-controlled source tarball using rpmbuild tarball mode (such as -ts, -ta, or -tb).
