CVE-2026-109932
Sicherheitslücken: 7800
A flaw in Node.js HMAC verification uses a non-constant-time comparison when validating user-provided signatures, potentially leaking timing information proportional to the number of matching bytes. Under certain threat models where high-resolution timing measurements are possible, this behavior could be exploited as a timing oracle to infer HMAC values. Node.js already provides timing-safe comparison primitives used elsewhere in the codebase, indicating this is an oversight rather than an intentional design decision. This vulnerability affects **20.x, 22.x, 24.x, and 25.x**.
A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOW_UPDATE frames on stream 0 (connection-level) that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up. This vulnerability affects HTTP2 users on Node.js 20, 22, 24 and 25.
> Fixed in OpenClaw 2026.3.24, the current shipping release. **Title** Mutating internal `/allowlist` chat commands missed `operator.admin` scope enforcement **CWE** CWE-862 Missing Authorization **CVSS v3.1** CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N Base score: **6.5 (Medium)** **Severity Assessment** Medium. This is a real authorization flaw in OpenClaw’s internal control plane. The issue does not require host access, trusted local state tampering, or multi-tenant assumptions, but exploitation does require an already authenticated internal Gateway caller with `operator.write`. **Impact** An authenticated internal Gatewa
A flaw in Node.js URL processing causes an assertion failure in native code when `url.format()` is called with a malformed internationalized domain name (IDN) containing invalid characters, crashing the Node.js process.
### Summary OpenCC versions before 1.2.0 contain two `CWE-125: Out-of-bounds Read` issues caused by length validation failures in UTF-8 processing. When handling malformed or truncated UTF-8 input, OpenCC trusted derived length values without enforcing the invariant that processed length must not exceed the remaining input buffer. This could result in out-of-bounds reads during segmentation or conversion. ### Details Two independent code paths in OpenCC failed to enforce the invariant: `matchedLength <= remainingLength` Both paths assumed derived length values were valid and within input bounds, but did not validate that assumption again
## Summary The prototype method blocklist in `lib/handlebars/internal/proto-access.js` blocks `constructor`, `__defineGetter__`, `__defineSetter__`, and `__lookupGetter__`, but omits the symmetric `__lookupSetter__`. This omission is only exploitable when the non-default runtime option `allowProtoMethodsByDefault: true` is explicitly set — in that configuration `__lookupSetter__` becomes accessible while its counterparts remain blocked, creating an inconsistent security boundary. `4.6.0` is the version that introduced `protoAccessControl` and the `allowProtoMethodsByDefault` runtime option. ## Description In `lib/handlebars/internal/proto
## Summary In `lib/handlebars/runtime.js`, the `container.lookup()` function uses `container.lookupProperty()` as a gate check to enforce prototype-access controls, but then discards the validated result and performs a second, unguarded property access (`depths[i][name]`). This Time-of-Check Time-of-Use (TOCTOU) pattern means the security check and the actual read are decoupled, and the raw access bypasses any sanitization that `lookupProperty` may perform. Only relevant when the **compat** compile option is enabled (`{compat: true}`), which activates `depthedLookup` in `lib/handlebars/compiler/javascript-compiler.js`. ## Description The
### Impact Multiple vulnerabilities were discovered in `tempo/charge` and `tempo/session` which allowed for undesirable behaviors, including: - Replaying `tempo/charge` transaction hashes across push/pull modes, across charge/session endpoints, and via concurrent requests - Performing free `tempo/charge` requests due to missing transfer log verification in pull-mode - Replaying `tempo/charge` credentials across routes via cross-route scope confusion (`memo`/`splits` not included in scope binding) - Manipulating the fee payer of a `tempo/charge` handler into paying for requests (missing sender signature before co-signing) - Bypassing `tempo/s
OpenClaw before 2026.3.12 embeds long-lived shared gateway credentials directly in pairing setup codes generated by /pair endpoint and OpenClaw qr command. Attackers with access to leaked setup codes from chat history, logs, or screenshots can recover and reuse the shared gateway credential outside the intended one-time pairing flow.
OpenClaw before 2026.3.8 contains a path traversal vulnerability in the skills download installer that validates the tools root lexically but reuses the mutable path during archive download and copy operations. A local attacker can rebind the tools-root path between validation and final write to redirect the installer outside the intended tools directory.
OpenClaw before 2026.3.11 contains an authorization bypass vulnerability in the gateway agent RPC that allows authenticated operators with operator.write permission to override workspace boundaries by supplying attacker-controlled spawnedBy and workspaceDir values. Remote operators can escape the configured workspace boundary and execute arbitrary file and exec operations from any process-accessible directory.
OpenClaw before 2026.2.17 creates session transcript JSONL files with overly broad default permissions, allowing local users to read transcript contents. Attackers with local access can read transcript files to extract sensitive information including secrets from tool output.
OpenClaw before 2026.3.13 allows bootstrap setup codes to be replayed during device pairing verification in src/infra/device-bootstrap.ts. Attackers can verify a valid bootstrap code multiple times before approval to escalate pending pairing scopes, including privilege escalation to operator.admin.
OpenClaw before 2026.3.13 reads and buffers Telegram webhook request bodies before validating the x-telegram-bot-api-secret-token header, allowing unauthenticated attackers to exhaust server resources. Attackers can send POST requests to the webhook endpoint to force memory consumption, socket time, and JSON parsing work before authentication validation occurs.
OpenClaw before 2026.3.11 contains an approval integrity vulnerability allowing attackers to execute rewritten local code by modifying scripts between approval and execution when exact file binding cannot occur. Remote attackers can change approved local scripts before execution to achieve unintended code execution as the OpenClaw runtime user.
OpenClaw before 2026.3.11 contains an approval integrity vulnerability where system.run approvals fail to bind mutable file operands for certain script runners like tsx and jiti. Attackers can obtain approval for benign script commands, rewrite referenced scripts on disk, and execute modified code under the approved run context.
OpenClaw before 2026.3.12 contains a weak authorization vulnerability in Zalouser allowlist mode that matches mutable group display names instead of stable group identifiers. Attackers can create groups with identical names to allowlisted groups to bypass channel authorization and route messages from unintended groups to the agent.
OpenClaw before 2026.3.12 contains an authentication bypass vulnerability in Feishu webhook mode when only verificationToken is configured without encryptKey, allowing acceptance of forged events. Unauthenticated network attackers can inject forged Feishu events and trigger downstream tool execution by reaching the webhook endpoint.
OpenClaw before 2026.3.11 contains an exec allowlist bypass vulnerability where matchesExecAllowlistPattern improperly normalizes patterns with lowercasing and glob matching that overmatches on POSIX paths. Attackers can exploit the ? wildcard matching across path segments to execute commands or paths not intended by operators.
OpenClaw before 2026.3.11 contains an authorization bypass vulnerability allowing authenticated operators with only operator.write permission to access admin-only browser profile management routes through browser.request. Attackers can create or modify browser profiles and persist attacker-controlled remote CDP endpoints to disk without holding operator.admin privileges.
