CVE-2026-93856

In OpenStack Cinder through 29.0.0, cross-project information disclosure can occur in the Messages API. A non-admin user with the project-scoped 'member' or 'reader' role making the Block Storage API v3.3 "List messages" call finds the non-expired user messages for other projects included in the response, resulting in the leakage of UUIDs of resources owned by other projects, in addition to the user message about the other projects' resources (which, by design, are sanitized generic messages). All Cinder deployments are affected.

CVE-2026-71195

In OpenStack Manila before 23.0.1, multiple Manila API operations on public shares do not verify that the caller owns the share. The API controllers authorize operations against the caller's own project context, then load a foreign public share without re-authorizing against the share's actual owner. This affects the following operations: allow_access: grant data-plane read/write access to another tenant's share; deny_access: revoke the owner's existing access rules; update_access: escalate access level (e.g., ro to rw); create_share_backup: exfiltrate share data via a backup created under the attacker's project; soft_delete: move a foreign s

Libmodulemd: libmodulemd: out-of-bounds read when emitting rpm-map artifacts

A flaw was found in libmodulemd. In the module stream v2 rpm-map emission path, an inner loop incorrectly uses the count of digest algorithms as its bound instead of the number of checksums in the current digest table. Crafted modulemd v2 metadata with multiple digest types can trigger an out-of-bounds read during YAML serialization, typically causing a crash and resulting in a denial of service.

Libmodulemd: libmodulemd: unbounded recursion when parsing nested xmd yaml

A flaw was found in libmodulemd. When parsing module metadata, the xmd field is converted into nested GVariant values through recursive YAML mapping and sequence helpers without a recursion-depth or node-count limit. An attacker who can supply crafted modulemd YAML with deeply nested xmd content can cause stack exhaustion or excessive resource consumption, resulting in a denial of service.

Libmodulemd: libmodulemd: missing decompressed-size limit when parsing compressed yaml

A flaw was found in libmodulemd. In builds with rpmio support enabled, compressed modulemd YAML is decompressed through a custom read handler that does not enforce a cumulative decompressed-size limit before parsing. An attacker who can supply a highly compressible compressed YAML file can cause excessive CPU and memory consumption, resulting in a denial of service.

Distrust compromised intermediate certificates in crypto/x509

On most platforms, Go uses the given system root certificates. However, in some narrower cases, the system trust stores may not be updated without further action. To defend against the narrower set of cases that may remain affected, a denylist was added in crypto/x509 to return an error when calling Verify with any of the known intermediate certificates that are no longer considered to be trustworthy.

Astral uv before 0.11.6 Arbitrary File Deletion via Wheel RECORD Entries

Astral uv before 0.11.6 contains a path traversal vulnerability that allows attackers to delete arbitrary files by supplying wheels with relative traversal paths in RECORD entries. Attackers can craft a malicious wheel whose RECORD references files outside the installation prefix, causing uv to delete those files when the user uninstalls the package.

• Обновитесь до 0.11.6

uv before 0.11.15 Arbitrary File Write via Entry Point Names

uv before 0.11.15 contains a path traversal vulnerability that allows malicious wheels to write files outside the scripts directory via crafted console_scripts or gui_scripts entry point names. Attackers who induce users to install a malicious wheel can place executables in PATH directories, shadowing or overwriting existing binaries for code execution.

Dulwich 0.22.5 before 1.2.8 Path Traversal via Stash Pop Symlinks

Dulwich from 0.22.5 before 1.2.8 contains a path traversal vulnerability in stash.py pop() that allows attackers to write arbitrary files outside the worktree through intermediate directory symlinks. Attackers can craft a malicious repository whose popped stash writes a payload into .git/hooks/post-checkout, achieving code execution on the next checkout.

• Обновитесь до 1.2.8
• Обновитесь до 1.2.8-1

Dulwich 0.23.1 before 1.2.8 Symlink Path Traversal via filter_branch Index Filter

Dulwich from 0.23.1 before 1.2.8 contains a path traversal vulnerability in CommitFilter._apply_index_filter() that allows attackers to write files outside the working directory via symlinks persisting between commits. Attackers can craft a repository where an ancestor commit's symlink redirects a descendant commit's file writes during filter_branch, enabling code execution by writing into .git/hooks.

Dulwich 0.24.0 before 1.2.8 Symlink Write-Through via porcelain.checkout paths

Dulwich from 0.24.0 before 1.2.8 contains a symlink following vulnerability in porcelain.checkout(paths=[...]) that allows attackers to write arbitrary files by abusing raw os.open without O_NOFOLLOW. Attackers can craft a repository where a worktree symlink points to .git/hooks/post-checkout, so restoring the file from a tag writes a malicious hook for code execution.

Dulwich before 1.2.9 Infinite Loop DoS via Pack.resolve_object

Dulwich before 1.2.9 contains a denial of service vulnerability in Pack.resolve_object that allows attackers to cause infinite recursion via self-referential OFS_DELTA objects. Attackers can supply a malicious packfile with an OFS_DELTA delta_offset of 0 to exhaust CPU during clone, fetch, or cat-file operations.

Dulwich before 1.2.9 Arbitrary File Write via DOS drive letter paths

Dulwich before 1.2.9 fails to validate DOS drive letter prefixes in Git tree path elements on Windows, allowing arbitrary file write. Attackers can craft a malicious repository with a tree entry named 'C:' that bypasses NTFS validation and writes files outside the worktree to achieve remote code execution.

FreeRDP 2.0.0 before 3.32.0 Proxy Improper TLS Certificate Validation

FreeRDP from 2.0.0 before 3.32.0 contains an improper certificate validation vulnerability in its proxy that accepts untrusted target TLS certificates when no verification module is configured. Network-positioned attackers can intercept the proxy's outbound connection and present a self-signed, wrong-hostname certificate to impersonate the RDP target and receive proxied session data.

FreeRDP 3.0.0 before 3.32.0 null-pointer dereference via emulated smartcard

FreeRDP 3.0.0 before 3.32.0 contains a null-pointer dereference in the smartcard emulation backend that accepts a null per-reader name in SCardGetStatusChange requests. A malicious RDP server can send a crafted reader-state entry with a null szReader, causing strcmp or _wcscmp to crash the client process.
