CVSS 3.5
CVE-2026-41079 WRITEUP MEDIUM
OpenPrinting CUPS: Heap out-of-bounds read in SNMP supply-level polling leaks stack memory to authenticated users
OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to 2.4.17, a network-adjacent attacker can send a crafted SNMP response to the CUPS SNMP backend that causes an out-of-bounds read of up to 176 bytes past a stack buffer. The leaked memory is converted from UTF-16 to UTF-8 and stored as printer supply description strings, which are subsequently visible to authenticated users via IPP Get-Printer-Attributes responses and the CUPS web interface. This vulnerability is fixed in 2.4.17.
CVSS 4.3
CVE-2026-6951 WRITEUP CRITICAL
Simple-git < 3.36.0 - Remote Code Execution
Versions of the package simple-git before 3.36.0 are vulnerable to Remote Code Execution (RCE) due to an incomplete fix for [CVE-2022-25912](https://security.snyk.io/vuln/SNYK-JS-SIMPLEGIT-3112221) that blocks the -c option but not the equivalent --config form. If untrusted input can reach the options argument passed to simple-git, an attacker may still achieve remote code execution by enabling protocol.ext.allow=always and using an ext:: clone source.

CVE-2026-41414 WRITEUP HIGH
Skim: Arbitrary code execution via pull_request_target fork checkout in pr.yml
Skim is a fuzzy finder designed to through files, lines, and commands. The generate-files job in .github/workflows/pr.yml checks out attacker-controlled fork code and executes it via cargo run, with access to SKIM_RS_BOT_PRIVATE_KEY and GITHUB_TOKEN (contents:write). No gates prevent exploitation - any GitHub user can trigger this by opening a pull request from a fork. This vulnerability is fixed with commit bf63404ad51985b00ed304690ba9d477860a5a75.
CVSS 7.4
CVE-2026-41415 WRITEUP CRITICAL
PJSIP: SIP Multipart CID URI Length Underflow
PJSIP is a free and open source multimedia communication library written in C. In 2.16 and earlier, there is an out-of-bounds read when parsing a malformed Content-ID URI in SIP multipart message body. Insufficient length validation can cause reads beyond the intended buffer bounds. This vulnerability is fixed in 2.17.
CVSS 9.1
CVE-2026-41416 WRITEUP HIGH
PJSIP: Asymmetric ptime integer overflow in Media Stream
PJSIP is a free and open source multimedia communication library written in C. In 2.16 and earlier, there is an integer overflow in media stream buffer size calculation when processing SDP with asymmetric ptime configuration. The overflow may result in an undersized buffer allocation, which can lead to unexpected application termination or memory corruption This vulnerability is fixed in 2.17.
CVSS 7.5
CVE-2026-41472 WRITEUP MEDIUM
CyberPanel < 2.4.4 Stored XSS via AI Scanner Dashboard
CyberPanel versions prior to 2.4.4 contain a stored cross-site scripting vulnerability in the AI Scanner dashboard where the POST /api/ai-scanner/callback endpoint lacks authentication and allows unauthenticated attackers to inject malicious JavaScript by overwriting the findings_json field of ScanHistory records. Attackers can inject JavaScript that executes in an administrator's authenticated session when they visit the AI Scanner dashboard, allowing them to issue same-origin requests to plant cron jobs and achieve remote code execution on the server.
CVSS 6.1
CVE-2026-41473 WRITEUP CRITICAL
CyberPanel < 2.4.4 Unauthenticated API Access via AI Scanner Endpoints
CyberPanel versions prior to 2.4.4 contain an authentication bypass vulnerability in the AI Scanner worker API endpoints that allows unauthenticated remote attackers to write arbitrary data to the database by sending requests to the /api/ai-scanner/status-webhook and /api/ai-scanner/callback endpoints. Attackers can exploit the lack of authentication checks to cause denial of service through storage exhaustion, corrupt scan history records, and pollute database fields with malicious data.
CVSS 9.1
CVE-2026-41894 WRITEUP HIGH
SiYuan < 3.6.5 - Double-Encoded Path Traversal
SiYuan is an open-source personal knowledge management system. Prior to 3.6.5, the fix for CVE-2026-30869 only added a denylist check (IsSensitivePath) but did not address the root cause — a redundant url.PathUnescape() call in serveExport(). An authenticated attacker can use double URL encoding (%252e%252e) to traverse directories and read arbitrary workspace files including the full SQLite database (siyuan.db), kernel log, and all user documents. This vulnerability is fixed in 3.6.5.
CVE-2026-42171 WRITEUP HIGH
Nullsoft Scriptable Install System <3.12 - Privilege Escalation
NSIS (Nullsoft Scriptable Install System) 3.06.1 before 3.12 sometimes uses the Low IL temp directory when executing as SYSTEM, allowing local attackers to gain privileges (if they can cause my_GetTempFileName to return 0, as shown in the references).
CVSS 7.8
CVE-2026-41681 WRITEUP CRITICAL
rust-openssl 0.10.39-0.10.77 - Memory Corruption
rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.39 to before 0.10.78, EVP_DigestFinal() always writes EVP_MD_CTX_size(ctx) to the out buffer. If out is smaller than that, MdCtxRef::digest_final() writes past its end, usually corrupting the stack. This is reachable from safe Rust. This vulnerability is fixed in 0.10.78.
CVSS 9.8
CVE-2026-41898 WRITEUP CRITICAL
rust-openssl 0.9.24-0.10.77 - Buffer Overflow
rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.24 to before 0.10.78, the FFI trampolines behind SslContextBuilder::set_psk_client_callback, set_psk_server_callback, set_cookie_generate_cb, and set_stateless_cookie_generate_cb forwarded the user closure's returned usize directly to OpenSSL without checking it against the &mut [u8] that was handed to the closure. This can lead to buffer overflows and other unintended consequences. This vulnerability is fixed in 0.10.78.
CVSS 9.8
CVE-2026-27596 WRITEUP HIGH
Exiv2 <0.28.8 - Memory Corruption
Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an out-of-bounds read was found in Exiv2. The vulnerability is in the preview component, which is only triggered when running Exiv2 with an extra command line argument, like -pp. The out-of-bounds read is at a 4GB offset, which usually causes Exiv2 to crash. This issue has been patched in version 0.28.8.

CVE-2026-41168 WRITEUP MEDIUM
pypdf has possible long runtimes for wrong size values in cross-reference and object streams
pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions prior to 6.10.1 can craft a PDF which leads to long runtimes. This requires cross-reference streams with wrong large `/Size` values or object streams with wrong large `/N` values. This has been fixed in pypdf 6.10.1. As a workaround, one may apply the changes from the patch manually.
CVSS 5.3
CVE-2026-41313 WRITEUP MEDIUM
pypdf: Possible long runtimes for wrong size values in incremental mode
pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions prior to 6.10.2 can craft a PDF which leads to long runtimes. This requires loading a PDF with a large trailer `/Size` value in incremental mode. This has been fixed in pypdf 6.10.2. As a workaround, one may apply the changes from the patch manually.
CVSS 6.5
CVE-2026-39920 WRITEUP CRITICAL
BridgeHead FileStore < 24A Apache Axis2 Default Credentials RCE
BridgeHead FileStore versions prior to 24A (released in early 2024) expose the Apache Axis2 administration module on network-accessible endpoints with default credentials that allows unauthenticated remote attackers to execute arbitrary OS commands. Attackers can authenticate to the admin console using default credentials, upload a malicious Java archive as a web service, and execute arbitrary commands on the host via SOAP requests to the deployed service.

CVE-2026-25775 WRITEUP CRITICAL
SenseLive X3050 Missing authentication for critical function
A vulnerability in SenseLive X3050’s remote management service allows firmware retrieval and update operations to be performed without authentication or authorization. The service accepts firmware-related requests from any reachable host and does not verify user privileges, integrity of uploaded images, or the authenticity of provided firmware.
CVSS 9.8
CVE-2026-27841 WRITEUP HIGH
SenseLive X3050 Cross-Site request forgery
A vulnerability in SenseLive X3050's web management interface allows state-changing operations to be triggered without proper Cross-Site Request Forgery (CSRF) protections. Because the application does not enforce server-side validation of request origin or implement CSRF tokens, a malicious external webpage could cause a user's browser to submit unauthorized configuration requests to the device.
