High [CVE-2026-72848] Server-Side Request Forgery and Information Disclosure via nested sitemap entries
SitemapLoader.parse_sitemap in langchain_community/document_loaders/sitemap.py applies the documented restrict_to_same_domain control only to leaf url entries. The loop over url elements filters cross-domain locations, but the loop over nested sitemap elements passes the child loc straight to self.scrape_all([loc.text], "xml"), which reaches WebBaseLoader.scrape_all and an aiohttp GET, with no domain comparison and no check for private, loopback or link-local destinations. An attacker who controls or influences an ingested sitemap can therefore point a nested sitemap entry at an internal address and make the server fetch it even when the deploying application set restrict_to_same_domain to True specifically to confine outbound requests. The fetched content is parsed and surfaces in the returned Documents, so internal responses are disclosed to the caller rather than merely requested. A flaw was found in langchain-community. This leads to Server-Side Request Forgery (SSRF) and information disclosure, as internal server responses are parsed and returned to the attacker. Red Hat severity: Important — CVSS 8.6 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N). Weakness: CWE-918. Affected products named by the advisory: Exploit Intelligence; Migration Toolkit for Applications 8; OpenShift Lightspeed; Red Hat Ansible Automation Platform 2; and 2 more.
High [CVE-2026-72818] Denial of Service via crafted URL input
The URLS regular expression in nltk/tokenize/casual.py, compiled into TweetTokenizer.WORD_RE and applied by TweetTokenizer.tokenize, contains a naked-domain branch whose domain-label prefix [a-z0-9]+(?:[.\-][a-z0-9]+)* is unbounded. Input consisting of many alternating label separators can be partitioned in exponentially many ways, and because the branch also requires a trailing top-level domain that such input never supplies, the engine explores those partitions before failing at each offset. A few kilobytes of input therefore consumes seconds to minutes of single-threaded CPU, and the HANG_RE substitution performed before matching does not collapse the pattern. TweetTokenizer is intended for tokenizing untrusted social-media text, so any service that applies it, or the module-level casual_tokenize, to submitted text can be stalled per request without authentication. Version 3.10.1 bounds the label repetition. A flaw was found in NLTK. The `TweetTokenizer` component, used for processing social media text, contains a regular expression vulnerability. A remote unauthenticated attacker can provide specially crafted input containing many alternating label separators, causing the regular expression to backtrack catastrophically. This can lead to a Denial of Service (DoS) by consuming significant CPU resources and stalling the application.
High [CVE-2026-69519] Azure Stack HCI Information Disclosure Vulnerability

High [CVE-2026-69242] Integer overflow leads to heap buffer overflow and arbitrary memory access
libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, a crafted many-band TIFF processed through VipsForeignLoadTiff can evade scanline validation in libvips/iofuncs/image.c and cause an integer overflow in vips_image_sanity. The resulting buffer-region calculation can access attacker-controlled negative offsets in mmap-resident allocations, allowing reads or writes of other image data, possible data disclosure through uncompressed.v output, and likely process crashes. Remote code execution has not been demonstrated but cannot be ruled out. This issue is fixed in version 8.18.3. A flaw was found in libvips. This overflow leads to a heap buffer overflow, allowing an attacker to access arbitrary memory locations with negative offsets. This is an Important flaw in libvips, where a specially crafted TIFF image can trigger an integer overflow, leading to a heap buffer overflow. This could allow an attacker to achieve arbitrary memory access, potentially resulting in data disclosure, denial of service, or remote code execution. The vulnerability requires local access or user interaction to process the malicious file. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-787.

High [CVE-2026-66787] cross-cluster DNS spoofing via unvalidated EndpointSlice and ServiceImport IPs
cross-cluster DNS spoofing via unvalidated EndpointSlice and ServiceImport IPs. Red Hat rates this important (CVSS 8.7). Weakness: CWE-345. Affected product named by the advisory: Red Hat Advanced Cluster Management for Kubernetes 2.
High [CVE-2026-63387] Off-by-one stack buffer overflow leading to denial of service or data corruption
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an off-by-one stack buffer overflow in evdns.c when dnsname_to_labels formats a name-bearing DNS record at the end of the 64 KB stack buffer allocated by evdns_server_request_format_response. The final-label check permits j plus label_len plus one to equal buf_len, after which the terminating null byte is written to buf[buf_len]. A crafted DNS server response containing PTR, CNAME, MX, NS, or SOA data can trigger the one-byte out-of-bounds write and crash or corrupt the process. A remote attacker could send a specially crafted DNS server response, which may lead to a crash or corruption of the process, resulting in a denial of service or potential information disclosure and integrity impact. Red Hat severity: Important — CVSS 8.6 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H). Weakness: CWE-787. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Hardened Images; Red Hat OpenShift Container Platform 4. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: libevent2.
High [CVE-2026-63384] Denial of Service via integer conversion error in `evtag_unmarshal_header`
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an incorrect integer conversion in event_tagging.c when evtag_unmarshal_header uses evtag_decode_int to decode an attacker-controlled uint32 payload length and returns it as a signed int. Values above INT_MAX become negative or truncated, and evtag_unmarshal_string can use the converted value in allocation sizing, producing a wrapped large allocation request and denial of service. A flaw was found in Libevent. An incorrect integer conversion in the `evtag_unmarshal_header` function allows a remote attacker to provide a specially crafted payload length. This can lead to a wrapped large allocation request, resulting in a denial of service (DoS) for the affected system. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-190. Affected Red Hat products: Red Hat Hardened Images; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat OpenShift Container Platform 4. Red Hat fixing advisory: RHSA-2026:60853. Affected products named by the advisory: Red Hat package: libevent2.
