An authentication bypass vulnerability exists in the generic opaque token validation path (validateOpaqueToken) of googleapis/mcp-toolbox. When the toolbox validates an opaque token via an OAuth 2.0 introspection endpoint (RFC 7662), it decodes the response into an introspectResp struct. However, the subsequent claim-checking logic (validateClaims) evaluates the issuer condition as if a.issuer != "" && iss != "". If the external OAuth provider's introspection response omits the optional iss (issuer) field completely, the variable iss defaults to an empty string. This causes the conditional block to evaluate to false and be skipped silently. Consequently, the application accepts tokens issued by unauthorized or unintended third-party identity providers.

An authentication bypass vulnerability exists in the generic opaque token validation path (validateOpaqueToken) of googleapis/mcp-toolbox. When verifying an unparsed opaque token via an OAuth 2.0 introspection endpoint (RFC 7662), the toolbox decodes the response into an introspectResp struct where the Active field is declared as a pointer to a boolean (*bool). The code only explicitly rejects a token if the response contains a populated active field set to false (if introspectResp.Active != nil && !*introspectResp.Active). If an introspection endpoint responds with a payload that completely omits the mandatory active key, the internal variable remains nil, causing the conditional check to short-circuit. As a result, Toolbox accepts authorization tokens missing the "active" field, granting access to protected tools and underlying data sources.

Path Traversal in Clasp impacting versions < 3.2.0 allows a remote attacker to perform remote code execution via a malicious Google Apps Script project containing specially crafted filenames with directory traversal sequences.

There exists a Path Traversal vulnerability in Safearchive on Platforms with Case-Insensitive Filesystems (e.g., NTFS). This allows Attackers to Write Arbitrary Files via Archive Extraction containing symbolic links. We recommend upgrading past commit f7ce9d7b6f9c6ecd72d0b0f16216b046e55e44dc

In createSessionInternal of PackageInstallerService.java, there is a possible to update a Device Policy Controller (DPC) into an invalid directory due to a path traversal error. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

There exists a path traversal vulnerability in the Android Google Search app. This is caused by the incorrect usage of uri.getLastPathSegment. A symbolic encoded string can bypass the path logic to get access to unintended directories. An attacker can manipulate paths that could lead to code execution on the device. We recommend upgrading beyond version 13.41

Improper Limitation of a Pathname to a Restricted Directory in DevTools in Google Chrome on Windows prior to 134.0.6998.35 allowed an attacker who convinced a user to install a malicious extension to bypass file access restrictions via a crafted Chrome Extension. (Chromium security severity: Medium)

In computeValuesFromData of FileUtils.java, there is a possible way to insert files to other apps' external private directories due to a path traversal error. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Inappropriate implementation in Web Share API in Google Chrome on Windows prior to 100.0.4896.60 allowed an attacker on the local network segment to leak cross-origin data via a crafted HTML page.

In openFile of BugreportContentProvider.java, there is a possible way to read and write unauthorized files due to a path traversal error. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

In multiple locations, there is a possible bypass of a file path filter designed to prevent access to sensitive directories due to incorrect unicode normalization. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.

In testGrantSlicePermission of SliceManagerTest.java, there is a possible permanent denial of service due to a path traversal error. This could lead to local denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.

In sm_mem_compat_get_vmm_obj of lib/sm/shared_mem.c, there is a possible arbitrary physical memory access due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Path traversal in Google Web Designer's template handling versions prior to 16.3.0.0407 on Windows allows attacker to achieve remote code execution by tricking users into downloading a malicious ad template

In update of MmsProvider.java, there is a possible way to change directory permissions due to a path traversal error. This could lead to local denial of service of SIM recognition with no additional execution privileges needed. User interaction is not needed for exploitation.

Arbitrary file write & potential privilege escalation exploiting zip slip vulnerability in Google Web Designer.

Arbitrary file write as the OSV-SCALIBR user on the host system via a path traversal vulnerability when using OSV-SCALIBR's unpack() function for container images. Particularly, when using the CLI flag --remote-image on untrusted container images.

FileBrowser Quantum is a free, self-hosted, web-based file manager. Versions prior to 1.3.2-stable, 1.4.0-beta and 1.4.1-beta are vulnerable to Path Traversal through the publicPatchHandler in backend/http/public.go which joins user-controlled fromPath and toPath body fields with the trusted d.share.Path BEFORE the downstream sanitizer runs. Because filepath.Join collapses .. segments during the join, the sanitizer in resourcePatchHandler never sees the traversal and the move/copy/rename operates on a path outside the shared directory. The same root-cause pattern was patched for the bulk DELETE endpoint as CVE-2026-44542 (GHSA-fwj3-42wh-8673), but the PATCH handler with the identical pattern was not updated. A public share link with AllowModify=true is sufficient to exploit this. Anyone holding such a link can move, copy, or rename arbitrary files within the share owner's source root. This issue has been fixed in versions 1.3.3-stable and 1.4.2-beta.

jj, or Jujutsu, is a Git-compatible VCS written in rust. In affected versions specially crafted Git repositories can cause `jj` to write files outside the clone. This issue has been addressed in version 0.23.0. Users are advised to upgrade. Users unable to upgrade should avoid cloning repos from unknown sources.
