NLTK's downloader in version 3.9.4 installs attacker-controlled package bytes by writing and potentially extracting downloaded content before enforcing SHA-256 or MD5 checksum validation. Any user or CI pipeline invoking `nltk.download()` against a compromised mirror, rogue proxy, or network-level MITM is at risk of silently installing malicious corpora or model files. No public exploit identified at time of analysis; active exploitation not confirmed (no CISA KEV listing). The AC:H CVSS metric correctly reflects the non-trivial infrastructure access an attacker must achieve, but the downstream trust propagation - NLP applications consuming poisoned models - amplifies the realistic impact beyond the base score.
CSV formula injection in Shlink 5.0.0-5.1.5 enables unauthenticated remote attackers to embed DDE or WEBSERVICE spreadsheet formulas into visit export data by supplying formula-triggering values in User-Agent, Referer, or request path headers targeting any short URL. The payload lies dormant in Shlink's visit log until an administrator exports the data as CSV and opens it in a spreadsheet application (Excel, LibreOffice Calc) with formula evaluation enabled, at which point the formula executes in the context of the administrator's machine. A public proof-of-concept repository exists; no CISA KEV listing is present, and no public exploit exploitation in the wild has been confirmed at time of analysis.
Reflected XSS in oaskit (Elixir/Plug OpenAPI request-validation library) versions 0.1.0 through 0.14.0 allows an unauthenticated remote attacker to execute arbitrary JavaScript in a victim's browser by inducing them to navigate to a crafted GET URL. The default HTML error handler interpolates request-controlled strings - object keys from query parameters or request bodies that appear in JSON Schema instance paths, and the raw Content-Type header - directly into HTML error pages without escaping. Both HTML error rendering and the vulnerable handler are enabled by default, so all applications following documented oaskit usage are exposed without any opt-in configuration; no public exploit tool is identified at time of analysis, though the advisory contains a working payload example demonstrating trivial exploitability.
Malformed theme application in the Misskey web client (versions 8.63.0 through pre-2026.5.4) triggers uncontrolled recursion (CWE-674), causing the browser client to slow down significantly or crash entirely. Unauthenticated network-reachable attackers can craft and distribute a malicious theme that, when applied by a victim user, produces a client-side denial of service. No public exploit code has been identified at time of analysis and this vulnerability is not listed in CISA KEV; active exploitation is not confirmed.
Stored cross-site scripting in OPNsense before 26.1.9 allows low-privileged authenticated attackers holding firewall rule management rights to inject arbitrary JavaScript into rule description fields via the filter API, which then executes in any authenticated administrator's browser when the Firewall Rules page is loaded. Impact is limited to subsequent-system effects - session hijacking or credential theft targeting other authenticated users - rather than direct host compromise. No confirmed active exploitation (not in CISA KEV) and no public exploit code identified at time of analysis; a vendor-released patch is available in OPNsense 26.1.9 as of June 2, 2026.
CSV formula injection in BaserCMS enables a remote unauthenticated attacker to embed malicious spreadsheet formulas into user-controlled fields within the CMS. When a privileged user exports affected data as a CSV and opens it in spreadsheet software such as Microsoft Excel or LibreOffice Calc, the injected formula executes in the context of that application on the victim's workstation. The CVSS Scope:Changed (S:C) rating reflects that impact escapes the web application boundary entirely, affecting the victim's local system. No active exploitation (KEV) has been confirmed and no public exploit code has been identified at time of analysis.
Stored cross-site scripting in OPNsense before 26.1.9 allows any authenticated user with certificate management access to plant a persistent JavaScript payload via the trust certificate API's description field. Once stored, the payload executes in the browser of every authenticated user who opens the Dashboard, because Certificates.js interpolates the raw description directly into an HTML attribute template literal without output encoding. No active exploitation has been confirmed (not in CISA KEV), and a vendor-released patch is available as of OPNsense 26.1.9.
Out-of-bounds write in the MediaTek Download Agent (DA) firmware component across eight chipset families allows an attacker with physical device access to trigger a local denial of service by sending a crafted payload while the device is in DA mode. Affected chipsets span mobile SoCs (MT6880, MT6890, MT6990, MT6988, MT6986, MT6813) and modem/automotive chipsets (MT2735, MT2737), broadening the potential device footprint across Android smartphones and connected vehicle platforms. No public exploit code exists, EPSS sits at the 6th percentile (0.16%), SSVC confirms no known exploitation, and the physical access prerequisite fundamentally constrains real-world risk.
Stack-based buffer overflow in OreSat Firmware v1.0 allows an attacker with physical access to the UART3 serial interface to crash the firmware by sending a crafted `edl fw_flash` command with an oversized filename argument. The CVSS vector (AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) confirms impact is strictly limited to availability - no confidentiality or integrity compromise is indicated. No public exploit code exists and no active exploitation has been identified; an EPSS score of 0.14% at the 4th percentile corroborates negligible automated exploitation probability.
Out-of-bounds read in MediaTek's GeniZone trusted execution environment (TEE) exposes memory on 17 affected chipset models to local information disclosure, but only after an attacker has already acquired System-level privilege. The vulnerability stems from a missing bounds check in the geniezone driver (CWE-125, Patch ID ALPS11036877), and is tracked by MediaTek as MSV-7132. No public exploit code exists and CISA has not listed this in KEV; with an EPSS of 0.14% (4th percentile) and SSVC exploitation status of 'none', this is a low-urgency finding despite the breadth of affected silicon.
Local information disclosure in the display subsystem of multiple MediaTek SoC chipsets results from a CWE-125 out-of-bounds read triggered by an integer overflow. Seventeen distinct chipsets are confirmed affected per the EUVD listing, spanning devices such as MT8910, MT8188, MT8768, and MT6991 - all prevalent in mid-range and budget Android hardware. Exploitation requires an attacker who has already attained System-level privilege on the device; no public exploit exists and EPSS sits at 0.14% (4th percentile), consistent with the SSVC exploitation rating of 'none'.
Local information disclosure in MediaTek's display subsystem exposes arbitrary kernel memory to a privileged local process due to a missing bounds check (CWE-125). Exploitation is limited to actors who have already obtained System-level privileges on a device running one of 17 affected MediaTek chipsets (MT6991, MT8676, MT8799, and others). No public exploit code and no active exploitation have been identified; EPSS sits at 0.14% (4th percentile), consistent with SSVC's 'none' exploitation status and 'no automatable' classification.
Information disclosure in the TFA (Trusted Firmware-A) component of MediaTek chipsets allows a local attacker who has already obtained System-level privilege to retrieve sensitive secure-world data without user interaction, due to a missing permission check (CWE-201). The flaw spans 39 distinct MediaTek chipsets across the MT6xxx and MT8xxx families, covering a broad range of Android smartphones, tablets, and embedded devices. No public exploit code or active exploitation has been identified; EPSS stands at 0.14% (4th percentile), consistent with the high privilege prerequisite limiting real-world impact.
Out-of-bounds write in MediaTek's Trusted Firmware-A (TFA) component allows a local attacker already holding System-level privilege to crash the device, causing a denial of service. Affected hardware includes MediaTek Dimensity and Helio chipsets MT6986D, MT6986, and MT6982VB. No public exploit code has been identified and CISA KEV does not list this vulnerability, consistent with its low EPSS score of 0.14% and SSVC exploitation status of none.
Out-of-bounds write in the wifi subsystem of MediaTek MT6890, MT6990, and MT6988 chipsets enables a local denial of service, crashing the wifi component or device. Exploitation requires that the attacker has already obtained System-level privilege on the affected device - an extremely high bar that makes this a post-exploitation nuisance rather than an initial access vector. EPSS sits at 0.13% (3rd percentile), no public exploit code exists, and the vulnerability is not listed in the CISA KEV catalog, all consistent with the substantial privilege prerequisite.
Out-of-bounds read in MediaTek's ccci (Cross Core Communication Interface) driver on multiple chipsets enables local denial of service by a System-privileged attacker. Affected chipsets include MT6813, MT6988, MT6982VB, MT6986D, and MT6986 - targeting mid-range and flagship Android SoC lines. No public exploit code exists and CISA has not added this to KEV; real-world impact is constrained by the high privilege prerequisite, making this a post-compromise availability risk rather than an initial access vector.
GNU tar's --one-top-level extraction mode fails to confine hardlink targets to the designated top-level directory, allowing a crafted archive to plant hardlinks that escape the intended extraction boundary. When combined with a preexisting symbolic link already present under the working directory, an attacker who can induce a victim to extract a malicious archive may read or write files outside the intended extraction scope on systems running affected RHEL versions (6 through 10) and Red Hat Hardened Images. No public exploit has been identified at time of analysis, and exploitation requires both user interaction and a specific environmental pre-condition, keeping real-world risk moderate despite GNU tar's ubiquitous deployment.
GNU tar's incremental restore path contains a TOCTOU race condition in dumpdir 'X' rename handling, allowing a local attacker with write access to a backed-up directory to redirect file operations outside the intended extraction root during a privileged restore. Successful exploitation can result in arbitrary file creation, rename, or overwrite - enabling privilege escalation on systems running Red Hat Enterprise Linux 6 through 10 and Red Hat Hardened Images. No public exploit is identified at time of analysis, and no CISA KEV listing exists; the CVSS score of 4.4 reflects the constrained attack prerequisites including a required race window and administrator-initiated restore.
