Out-of-bounds reads and a process crash in Nmap through 7.99 can be triggered remotely by any host that is being scanned, or by an on-path attacker, via a crafted IPv6 packet with a truncated extension header. The root cause is an integer underflow in the `ipv6_get_data_primitive` function (libnetutil/netutil.cc) where an insufficiently strict bounds check allows the extension-header walk pointer to advance past the captured packet buffer, causing the remaining-length subtraction to wraparound to a very large value. A publicly available exploit proof-of-concept exists; this vulnerability is not currently listed in the CISA KEV catalog.
HTTP request/response smuggling in nghttpx (the reverse proxy component of nghttp2 through 1.69.0) allows unauthenticated remote attackers to poison shared backend keep-alive connections by crafting an HTTP/1.1 Upgrade request that simultaneously carries a Content-Length header and body. When nghttpx forwards this ambiguous message to a backend and re-adds Connection and Upgrade headers while passing Content-Length verbatim, a backend that resolves the parsing ambiguity in the attacker's favor treats the body as a separate, attacker-controlled HTTP request - enabling cross-client response-queue poisoning. A publicly available proof-of-concept exploit exists; no CISA KEV listing at time of analysis.
Path traversal in ANTLR4 up to 4.13.2 exposes arbitrary file read via the tokenVocab grammar option handler. The vulnerable function getImportedVocabFile in TokenVocabParser.java fails to sanitize user-controlled grammar option values, allowing an attacker to supply a crafted .g4 grammar file that causes the tool to read files outside the intended working directory. A publicly available proof-of-concept exploit exists (GitHub issue reference), and no vendor patch has been released - the vendor did not respond to disclosure. No active exploitation is confirmed in CISA KEV, but the CVSS 4.0 E:P flag confirms exploit code is public.
SQL injection in SourceCodester Class and Exam Timetabling System 1.0 allows unauthenticated remote attackers to manipulate the `course_year_section` parameter on the `/preview6.php` endpoint, enabling unauthorized read and write access to the underlying database. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires no authentication and no special conditions, and a public proof-of-concept has been disclosed on GitHub. While not listed in CISA KEV, the trivially low attack complexity combined with POC availability raises the realistic exploitation risk above what the 5.5 medium score alone implies.
SQL injection in SourceCodester Class and Exam Timetabling System 1.0 exposes the `/preview.php` endpoint to remote unauthenticated exploitation via the unsanitized `course_year_section` parameter, allowing arbitrary SQL query execution against the backend database. A public proof-of-concept exploit has been published on GitHub, materially lowering the barrier to exploitation. Impact is rated low-to-partial across confidentiality, integrity, and availability, bounded by the database account's privileges, and no vendor patch has been identified at time of analysis.
Code injection in ANTLR4's Grammar Action Block Handler allows remote attackers to execute arbitrary code by supplying a crafted grammar file processed by the tool. All versions up to and including 4.13.2 are affected via the OutputFile.java code generation pathway. A public proof-of-concept exploit exists on GitHub (no KEV listing), though the vendor has not acknowledged or patched the issue, leaving users without an official fix.
SQL injection in yashpokharna2555's restaurent-management-system exposes the /forgotpassword.php endpoint to unauthenticated remote exploitation via the POST email parameter, allowing attackers to execute arbitrary SQL against the backend database. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms no authentication or preconditions are required, and a public exploit is referenced in GitHub issue #3. The project has no versioning scheme and the maintainer has not responded to the disclosure, meaning no patch is available and all deployed instances remain vulnerable.
SQL injection in SourceCodester Class and Exam Timetabling System 1.0 exposes the `/preview7.php` endpoint to unauthenticated remote exploitation via unsanitized input in the `course_year_section` parameter. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms zero-friction remote exploitation with no authentication or user interaction required. No public exploit identified at time of analysis is incorrect here - a publicly available exploit exists (GitHub issue referenced in references), elevating urgency despite the absence of a CISA KEV listing.
SQL injection in SourceCodester Class and Exam Timetabling System 1.0 exposes any publicly reachable deployment to unauthenticated database manipulation via the unsanitized `sy` parameter in /archive.php. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N) confirms remote exploitation with no prerequisites, yielding low-to-moderate impact across confidentiality, integrity, and availability of the underlying database. A publicly available proof-of-concept exploit exists on GitHub (referenced via VulDB submission 838189), lowering attacker skill requirements, though no CISA KEV listing indicates mass exploitation has not been confirmed at time of analysis.
Mark-of-the-Web protection is bypassed in 7-Zip for Windows 26.02 and earlier when extracting crafted RAR5 archives, allowing an attacker to strip the Internet-zone marker (ZoneId=0) and spoof the extracted file's data stream content - directly defeating SmartScreen and Windows attachment warnings. The bypass exploits a gap between 7-Zip's exact-string guard ('Zone.Identifier') and the NTFS-canonical equivalent (':Zone.Identifier:$DATA') that a RAR5 STM record can supply; a second STM record ('::$DATA') additionally overwrites the default file data stream for content spoofing. A publicly available proof-of-concept exists; no vendor-released patched version has been confirmed at the time of analysis.
NULL pointer dereference in the Zephyr Bluetooth LE Audio Basic Audio Profile unicast client crashes devices running Zephyr v4.3.0 and v4.4.0 (and earlier) when connected to a malicious or buggy remote ASCS server. The handler unicast_client_ep_qos_state() writes attacker-controlled QoS fields through stream->qos without verifying the pointer is non-NULL - a condition that legitimately exists during the window between bt_bap_stream_config() and unicast_group_add_stream(). No public exploit code has been identified and this vulnerability is not listed in CISA KEV, but CVSS adjacency (AV:A) and no-auth (PR:N) make it exploitable by any device within Bluetooth LE radio range acting as a rogue ASCS server.
Authorization bypass in GLPI 11.0.5 through 11.0.7 exposes restricted documents to unauthorized network-based access via a manipulable docid parameter in the document download handler. The vulnerability resides in the Document::canViewFile authorization check within front/document.send.php, where an attacker can tamper with the docid argument to circumvent document-level access controls and retrieve files they are not permitted to view. No public exploit has been identified at time of analysis, and EPSS data was not provided; however, the remote network vector with no required privileges raises concern for exposed GLPI deployments.
