The profile of a Liberapay team member contained a link to an expired Twitter account, creating a broken link hijacking vulnerability. The expired Twitter account link was displayed on the member's Liberapay profile and donation page, falsely confirming to donors that the account was legitimate a...

curl: CVE-2026-8458: wrong reuse for different services

Summary: I found an incomplete-fix variant of CVE-2026-5545 in curl/libcurl 8.20.0. libcurl 8.20.0 still wrongly reuses an HTTP Negotiate-authenticated connection for a later request to the same host even when the requested service principal changes via CURLOPTSERVICENAME / --service-name. In my...

curl: Shared HSTS cache accessed without lock

This is finding F5 in Andrew's report https://github.com/curl/curl/blob/455bebc2c7/lib/hsts.cL160-L168 https://github.com/curl/curl/blob/455bebc2c7/lib/http.cL3571 https://github.com/curl/curl/blob/455bebc2c7/lib/url.cL1441 https://github.com/curl/curl/blob/455bebc2c7/lib/url.cL265...

curl: CVE-2026-8286: wrong STARTTLS connection reuse

A vulnerability was found in the Curl library that allowed a plain-text connection to reuse an existing SSL-upgraded connection without verifying the SSL configuration. This could lead to a man-in-the-middle attack if an attacker was able to intercept the initial STARTTLS upgrade. The issue was...

curl: CURLOPT_PROXY_CRLFILE / CURLOPT_PROXY_ISSUERCERT / CURLOPT_PROXY_ISSUERCERT_BLOB silently ignored on backends that don't support them

From the Mythos report 2026-05-06 F1. CURLOPTPROXYCRLFILE / CURLOPTPROXYISSUERCERT / CURLOPTPROXYISSUERCERTBLOB silently ignored on backends that don't support them — severity Low https://github.com/curl/curl/blob/455bebc2c7/lib/setopt.cL1786-L1797...

curl: mbedTLS private-key blob null-termination asymmetry in lib/vtls/mbedtls.c (mbed_load_privkey)

Summary: In lib/vtls/mbedtls.c, function mbedloadprivkey lines 653-738 passes raw sslkeyblob-data and sslkeyblob-len directly to mbedtlspkparsekey at lines 706-708 mbedTLS 4.x branch and 718-722 mbedTLS 3.x branch, without ensuring null-termination. The mbedTLS API contract for mbedtlspkparsekey...

PortSwigger Web Security: UI Consent Bypass via Comma Injection in `addAutoApproveTarget` — User-Approval Dialog and Persistence Layer Disagree on Target Scope, Yielding Authen

A vulnerability was discovered in Burp Suite MCP Server BApp v1.2.1 where the addAutoApproveTarget function failed to validate the hostnames passed to it. This allowed a malicious MCP client to inject a comma-separated hostname, which was then persisted as multiple independent allow-list entries...

GitHub: Able to bypass authorization logic and gain more access then intended

A UI misrepresentation vulnerability was identified in GitHub Enterprise Server that allowed an OAuth application to gain unintended access to an organization's runner management. The vulnerability was fixed in versions 3.21.2, 3.20.4, 3.19.8, 3.18.11, 3.17.17, and 3.16.20. This vulnerability was...

Rocket.Chat: IDOR: autotranslate.translateMessage Full Message Content Leak

The /api/v1/autotranslate.translateMessage endpoint allowed any authenticated user to retrieve the full content of any message from any room, including private groups, direct messages, and channels. The endpoint fetched the message without performing a room access check, returning the complete...

curl: MQTT CONNACK Packet Type Bypass leads to RCE via Malicious Broker

Summary: mqttverifyconnack in lib/mqtt.c never checks that the received packet type is actually a CONNACK 0x20. The constant MQTTMSGCONNACK is commented out at line 45, making the check impossible to write. A malicious broker can send any packet — e.g. PUBACK 0x40 — with remaininglength=2 and...

PortSwigger Web Security: Burp Suite Professional: browser-powered crawl can write attacker-controlled files through file input handling

A vulnerability was discovered in Burp Suite Professional 2026.3.3 on Windows. When Burp Scanner's browser-powered crawler crawled an attacker-controlled website, the website could force Burp to write an attacker-controlled file to an attacker-controlled local path. The issue was caused by Burp's...

curl: Potential Resource Leak in tool_parsecfg.c at line 279 during fileerror

Summary: A resource leak was identified in src/toolparsecfg.c using the Clang Static Analyzer. When a file error occurs fileerror is true during config parsing, the function returns PARAMREADERROR without ensuring the file stream is properly closed, leading to a potential file descriptor leak...

curl: wcurl treats some URL operands after -- as curl options

I found that wcurl does not always keep operands after -- in a pure URL-data context. The documented way to pass curl options through wcurl is --curl-options, but a value supplied as a URL operand can still reach the final curl command as an option, for example wcurl -- "--url=file:///...". A...

curl: libcurl 8.20.0 incomplete fix for CVE-2026-7168: changing only CURLOPT_PROXYPORT leaks stale Proxy Digest auth to a different proxy

Summary: I found an incomplete-fix variant of CVE-2026-7168 in curl 8.20.0. The 8.20.0 fix clears state.proxydigest / state.authproxy when CURLOPTPROXY changes, but not when only CURLOPTPROXYPORT changes. On the same easy handle, request 1 through proxyA CURLOPTPROXYPORT=18197 learns Proxy Digest...

curl: MQTT state machine confusion: PINGRESP/DISCONNECT with non-zero remaining_length dispatches to stale nextstate

Summary: In lib/mqtt.c, the state machine in mqttdoing lines 894-911 in curl 8.20.0 does not validate that PINGRESP 0xD0 and DISCONNECT 0xE0 packets have remaininglength == 0 as required by MQTT 3.1.1 spec sections 3.13.1 and 3.14.1. A malicious broker can send a PINGRESP fixed header with non-ze...

AWS VDP: bedrock-mantle.api.aws accepts Bedrock API keys outside the IAM Deny, CloudTrail signal, and invocation logging AWS publishes for Bedrock keys

A second Bedrock API key-accepting service plane called "bedrock-mantle" was discovered. This plane was not described in AWS's customer-facing Bedrock documentation. As a result, the AWS-published security controls to detect and prevent Bedrock API key abuse failed to apply to the bedrock-mantle...

Tor: Malicious Conflux Endpoint Can Leave Stale Global OOO Queue Accounting After Teardown

A vulnerability was discovered in Tor's Conflux OOO queue accounting. The vulnerability could cause the global OOO queue byte counter to remain inflated after a Conflux set was torn down, even though the memory had already been freed. This was due to a lack of accounting updates during the teardo...

Monero: SpendProofV1 txid-substitution: get_spend_proof/check_spend_proof do not verify returned transaction hash

A vulnerability was discovered in the Monero project where the getspendproof and checkspendproof functions do not verify the returned transaction hash against the requested transaction ID. This allows a malicious or compromised daemon to provide a valid serialized transaction body for a different...
