Prototype pollution in Axios 1.x (prior to 1.15.1) and 0.x (prior to 0.31.1) enables HTTP header injection attacks when any dependency in the application pollutes Object.prototype with specific properties (getHeaders, append, pipe, on, once, Symbol.toStringTag). Attackers exploit the HTTP adapter's duck-type checking to inject arbitrary headers into outbound HTTP requests, potentially leading to authentication bypass, session hijacking, or cache poisoning. EPSS data unavailable; no confirmed active exploitation (CISA KEV) at time of analysis. Publicly available exploit code exists per vendor advisory GHSA-6chq-wfr3-2hj9.
GitHub Actions workflow injection in Skim's CI pipeline allows remote code execution with elevated privileges when any GitHub user opens a pull request from a fork. The vulnerable generate-files job automatically checks out and executes attacker-controlled Rust code (via cargo run) with access to SKIM_RS_BOT_PRIVATE_KEY secret and GITHUB_TOKEN with contents:write permissions, enabling repository compromise. User interaction (maintainer reviewing the PR) is required for context, though the exploit executes automatically on PR creation. Patch available via commit bf63404, no active exploitation confirmed at time of analysis.
Out-of-bounds memory access in Linux Kernel's KVM subsystem for LoongArch architecture allows local authenticated attackers with low privileges to read limited kernel memory and cause system crashes. The vulnerability stems from improper handling of empty EIOINTC coremap values in eiointc_update_sw_coremap(), resulting in invalid array indexing into kvm_arch::phyid_map::phys_map[]. While CVSS rates this 7.3 HIGH, the EPSS score of 0.02% (4th percentile) indicates minimal real-world exploitation activity. No active exploitation (not in CISA KEV) or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.18.21, 6.19.11, 7.0, and mainline).
Path traversal vulnerabilities in AWS Tough (a Rust TUF client library) versions prior to 0.22.0 enable authenticated users with delegated signing privileges to write arbitrary files outside intended repository directories, bypassing incomplete fixes from previous security patches. The flaws exist in three distinct code paths: absolute target names in copy_target/link_target operations, symlinked parent directories in save_target, and symlinked metadata filenames in SignedRole::write. AWS has released patches in tough-v0.22.0 and tuftool-v0.15.0 that implement post-resolution path containment verification. No public exploit code or active exploitation confirmed at time of analysis, though CVSS 7.1 HIGH reflects significant integrity impact when exploited.
Directory traversal in SiYuan personal knowledge management system allows authenticated attackers to read arbitrary workspace files via double URL encoding bypass. The vulnerability stems from an incomplete fix for CVE-2026-30869 that added only denylist validation without removing a redundant url.PathUnescape() call in serveExport(). Attackers can use %252e%252e encoding to access sensitive files including the complete SQLite database (siyuan.db), kernel logs, and all user documents. EPSS data not available for this recent CVE; publicly available exploit code exists (GitHub commit demonstrates exploitation technique).
Authenticated users in Kirby CMS can bypass permission controls to create unauthorized pages, files, and users by injecting malicious blueprint configuration during model creation. Versions prior to 4.9.0 and 5.4.0 fail to sanitize the 'blueprint' property in creation requests, allowing attackers with low-privilege accounts to override developer-defined authorization policies by setting 'create' => true in dynamic options. Patches are available in Kirby 4.9.0 and 5.4.0, which implement filtering of blueprint properties during normalization.
Metadata integrity bypass in AWS tough (TUF client library) before v0.22.0 allows authenticated users with delegated signing authority to poison local metadata caches by bypassing expiration, hash, and length validation checks. The vulnerability exists because load_delegations skips specification-mandated integrity checks applied to top-level targets metadata, enabling malicious delegated signers to inject invalid metadata. AWS has released patches in tough-v0.22.0 and tuftool-v0.15.0. CVSS 7.1 reflects network vector but high attack complexity (AT:P indicates specialized conditions). No public exploit or active exploitation confirmed at time of analysis, though authentication bypass tag suggests significant trust boundary violation.
Uninitialized memory read in Linux kernel's rtl8723bs Wi-Fi driver allows adjacent network attackers to cause denial of service or potentially corrupt integrity through malformed BIP (Broadcast/Multicast Integrity Protocol) frames. The vulnerability affects the staging rtl8723bs driver where only 6 bytes are copied into an 8-byte variable during BIP verification, leaving 2 bytes uninitialized. Patches available across multiple stable kernel versions (6.12.83, 6.18.24, 6.19.14, 7.0.1). EPSS score of 0.02% (5th percentile) indicates low observed exploitation probability. Not listed in CISA KEV, and no public exploit identified at time of analysis.
Out-of-bounds kernel heap read in the Linux kernel's CIFS/SMB client (check_wsl_eas() extended-attribute parser) lets a malicious or compromised SMB server leak up to 8 bytes of adjacent kernel heap into the WSL xattr name comparison, influencing which WSL extended attribute the returned data is interpreted as. The root cause is an off-by-8 bounds check (CWE-125) that measures the EA end from the struct base instead of ea->ea_data, so the trailing name and value bytes of the last EA are read past the end of the response iov. There is no public exploit identified at time of analysis, EPSS risk is negligible (0.02%), and it is not on CISA KEV; patched kernels are already available.
Denial of service in the Linux kernel's s390 (IBM Z) secure-execution memory subsystem allows storage donated to the Ultravisor to trigger unresolvable secure-storage-access exception loops. Because donated pages lack the PG_arch_1 bit, the prior fixup path (arch_make_folio_accessible()) returned immediately without exporting the page, causing the fault to repeat indefinitely. No public exploit identified at time of analysis; EPSS is negligible (0.02%, 4th percentile) and exploitation is confined to s390 Protected Virtualization guests.
Signature duplication in AWS Tough TUF client prior to v0.22.0 allows authenticated attackers to bypass threshold signature requirements for delegated role metadata by reusing a single valid signature multiple times. The flaw undermines TUF's multi-signature integrity model, enabling acceptance of forged metadata with reduced cryptographic validation. Vendor patch available (tough-v0.22.0, tuftool-v0.15.0). No public exploit code or active exploitation confirmed at time of analysis, but CVSS 7.0 reflects high integrity impact to both vulnerable and downstream systems.
