OpenWrt Project is a Linux operating system targeting embedded devices. In versions prior to 24.10.6 and 25.12.1, the mdns daemon has a Stack-based Buffer Overflow vulnerability in the match_ipv6_addresses function, triggered when processing PTR queries for IPv6 reverse DNS domains (.ip6.arpa) received via multicast DNS on UDP port 5353. During processing, the domain name from name_buffer is copied via strcpy into a fixed 256-byte stack buffer, and then the reverse IPv6 request is extracted into a buffer of only 46 bytes (INET6_ADDRSTRLEN). Because the length of the data is never validated before this extraction, an attacker can supply input larger than 46 bytes, causing an out-of-bounds write. This allows a specially crafted DNS query to overflow the stack buffer in match_ipv6_addresses, potentially enabling remote code execution. This issue has been fixed in versions 24.10.6 and 25.12.1.

OpenClaw versions prior to 2026.3.1 contain a server-side request forgery vulnerability in web_search citation redirect resolution that uses a private-network-allowing SSRF policy. An attacker who can influence citation redirect targets can trigger internal-network requests from the OpenClaw host to loopback, private, or internal destinations.

OpenClaw versions prior to 2026.2.24 contain an improper path validation vulnerability in sandbox media handling that allows absolute paths under the host temporary directory outside the active sandbox root. Attackers can exploit this by providing malicious media references to read and exfiltrate arbitrary files from the host temporary directory through attachment delivery mechanisms.

OpenWrt Project is a Linux operating system targeting embedded devices. In versions prior to 24.10.6 and 25.12.1, the mdns daemon has a Stack-based Buffer Overflow vulnerability in the parse_question function. The issue is triggered by PTR queries for reverse DNS domains (.in-addr.arpa and .ip6.arpa). DNS packets received on UDP port 5353 are expanded by dn_expand into an 8096-byte global buffer (name_buffer), which is then copied via an unbounded strcpy into a fixed 256-byte stack buffer when handling TYPE_PTR queries. The overflow is possible because dn_expand converts non-printable ASCII bytes (e.g., 0x01) into multi-character octal representations (e.g., \001), significantly inflating the expanded name beyond the stack buffer's capacity. A crafted DNS packet can exploit this expansion behavior to overflow the stack buffer, making the vulnerability reachable through normal multicast DNS packet processing. This issue has been fixed in versions 24.10.6 and 25.12.1.

OpenClaw versions prior to 2026.2.19 contain an allowlist bypass vulnerability in the exec safeBins policy that allows attackers to write arbitrary files using short-option payloads. Attackers can bypass argument validation by attaching short options like -o to whitelisted binaries, enabling unauthorized file-write operations that should be denied by safeBins checks.

OpenClaw versions prior to 2026.2.25 contain a symlink traversal vulnerability in the agents.files.get and agents.files.set methods that allows reading and writing files outside the agent workspace. Attackers can exploit symlinked allowlisted files to access arbitrary host files within gateway process permissions, potentially enabling code execution through file overwrite attacks.

OpenClaw versions prior to 2026.2.19 contain a local command injection vulnerability in Windows scheduled task script generation due to unsafe handling of cmd metacharacters and expansion-sensitive characters in gateway.cmd files. Local attackers with control over service script generation arguments can inject arbitrary commands by providing metacharacter-only values or CR/LF sequences that execute unintended code in the scheduled task context.

OpenClaw versions prior to 2026.2.26 contain a metadata spoofing vulnerability where reconnect platform and deviceFamily fields are accepted from the client without being bound into the device-auth signature. An attacker with a paired node identity on the trusted network can spoof reconnect metadata to bypass platform-based node command policies and gain access to restricted commands.

OPEXUS eComplaint and eCASE before 10.2.0.0 do not correctly sanitize the contents of first and last name fields in a user profile. An authenticated attacker can inject parts of an XSS payload in their first and last name fields. The payload is executed when the user's full name is rendered. The attacker can run script in the context of a victim's session.

OpenClaw versions prior to 2026.2.19 contain a path traversal vulnerability in the stageSandboxMedia function that accepts arbitrary absolute paths when iMessage remote attachment fetching is enabled. An attacker who can tamper with attachment path metadata can disclose files readable by the OpenClaw process on the configured remote host via SCP.
