CVE-2026-123037

Ansible-core: user module generate_ssh_key follows a symlinked ~/.ssh enabling local privilege escalation (incomplete fix of cve-2024-9902)

A flaw was found in the ansible-core user module. When generate_ssh_key is enabled, User.ssh_key_gen() guards the key files against symlinks but checks the ~/.ssh directory only with os.path.exists(). An unprivileged user on a managed node who replaces their ~/.ssh with a symlink to an existing root-writable directory causes the privileged module to write the generated key pair through the symlink and then chown both files to that user. Because such files can be dropped into directories processed by schedulers (e.g. /etc/cron.daily) or dynamic MOTD (/etc/update-motd.d), the user can escalate to root on the managed node. This is an incomplete fix of CVE-2024-9902.

Keycloak-core: keycloak-core: saml adapter does not bind signed assertions to the configured identity provider issuer

A flaw was found in the SAML adapter component of Keycloak, which is used to secure applications with SAML-based authentication. The adapter fails to verify that the issuer of a signed SAML assertion matches the expected identity provider configured for the application. If multiple identity providers share the same trusted signing key, an attacker who controls one of those providers can create a validly signed assertion to log into the application as any user, potentially gaining full administrative control.

Resteasy-core: resteasy sourceprovider remote unauthenticated file read

A flaw was found in RESTEasy's SourceProvider. This vulnerability allows an unauthenticated attacker to perform an unauthenticated remote file read. By sending a specially crafted XML body with a DOCTYPE declaration referencing external entities to an endpoint that accepts application/xml and returns Source or StreamSource, the server can be tricked into resolving the entity and including sensitive file contents in the HTTP response. This is due to the SourceProvider.writeTo() method creating a SAXParser without disabling external entity resolution, leading to an XML External Entity (XXE) vulnerability.

Libsolv: heap buffer overflow in libsolv repopagestore via unchecked decompression of malicious .solv page data

A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.

Libsolv: libsolv: out-of-bounds write in repo_write() via unvalidated directory id from vertical/paged .solv filelist data

A flaw was found in libsolv, a dependency-resolution library used by RPM-based package managers such as dnf and zypper to work with .solv repository cache files. When libsolv rewrites a .solv cache file, it reads directory-id values from the file's compressed filelist data without validating that they fall within the expected range. A corrupted or specially crafted .solv cache file (for example, one left in a torn state after an unclean system shutdown) can cause an out-of-bounds memory write when a tool such as dnf, yum, or zypper next processes it. Successful exploitation is expected to result in a crash of the affected tool (denial of service); it is not expected to allow arbitrary code execution because the out-of-bounds write always stores a fixed, non-attacker-controlled value.

Rpm: command injection in rpmuncompress dountar() via unescaped archive top-level directory name in popen() shell command

A command injection vulnerability was discovered in the `rpmuncompress` utility of RPM. When extracting certain archive formats (ZIP, 7z, GEM) to a specified destination directory, the tool inserts the archive's top-level folder name into a shell command without properly sanitizing it. A specially crafted archive containing shell metacharacters in its folder name can execute arbitrary commands as the user running the extraction.

Golang-fips: golang fips zeroed buffer

A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum.  It is also possible to force a derived key to be all zeros instead of an unpredictable value.  This may have follow-on implications for the Go TLS stack.

Ansible-core: ansible-core: ansible-galaxy collection install symlink path escape allows arbitrary file write / code execution

A flaw was found in ansible-core. When installing a collection with `ansible-galaxy collection install`, the archive extractor validates member paths using lexical path normalisation (os.path.abspath) instead of resolving symbolic links (os.path.realpath), and it performs no containment check on symlink-typed directory members before creating them. A crafted collection tarball can chain symlink directory entries so that a subsequent file member is written outside the intended destination directory. This allows an attacker who can get a victim to install a malicious collection to overwrite arbitrary files with the privileges of the user running ansible-galaxy, leading to code execution on the control node. This is a bypass of the fix for CVE-2020-10691.

Ansible-core: argument injection in ansible-galaxy collection install via git clone (incomplete fix for cve-2026-11332)

A flaw was found in ansible-core. The _extract_collection_from_git() function in ansible-core's concrete_artifact_manager.py constructs git clone commands without a '--' (end-of-options) separator before user-supplied URLs when installing collections from git sources. An attacker who provides a crafted collection source URI containing git argument injection payloads can achieve arbitrary command execution when a user runs 'ansible-galaxy collection install' with the malicious source. This is an incomplete fix for CVE-2026-11332, which hardened the role install path but missed the equivalent collection install code path.

Yggdrasil: local privilege escalation in yggdrasil

A flaw was found in Yggdrasil, which acts as a system broker, allowing the processes to communicate to other children's "worker" processes through the DBus component. Yggdrasil creates a DBus method to dispatch messages to workers. However, it misses authentication and authorization checks, allowing every system user to call it. One available Yggdrasil worker acts as a package manager with capabilities to create and enable new repositories and install or remove packages. This flaw allows an attacker with access to the system to leverage the lack of authentication on the dispatch message to force the Yggdrasil worker to install arbitrary RPM packages. This issue results in local privilege escalation, enabling the attacker to access and modify sensitive system data.
